Goyen Pulse Valve Replacement: 2026 Equivalent Guide

Before you swap a valve, define what a replacement has to preserve

A pulse valve does three things when it opens: it admits clean compressed air into the filter housing, it pressurises the venturi, and the venturi creates the shock wave that shakes dust off the bag. Everything about the replacement must preserve that sequence, which is why two valves that look identical on the bench can behave very differently on the tank.

So before anything is ordered, write down five things about the valve being replaced: the orifice and port size, whether the coil sits on the valve or on a separate pilot, the coil voltage and connector, the diaphragm and seal material, and the pressure and temperature at that position. Those five come from published product data rather than a photograph, and they are the subject of the rest of this guide.

The Goyen families published here, and the naming trap between CA and RCA

The naming convention is where most replacement mistakes start, and two conventions run through the published range.

CA and RCA describe the pilot arrangement. A CA valve is the integral pilot type: the solenoid coil sits on the valve body and the valve is wired and piped as one unit. An RCA valve is remotely piloted: the coil sits on a separate pilot valve or pilot box, and the body only carries a small pilot port that receives the pilot air.

The suffix describes how the valve connects. T is a threaded body, MM is the manifold or tank-mounted version, DD is the remote-pilot type with compression fitting connections, FS is a flanged inlet, and the trailing digits in products such as the RCAC25T4 refer to the Series-4 pattern, published here as a Goyen equivalent.

That leaves the equivalences a baghouse buyer actually meets. A 1-inch threaded integral pilot valve is the CA-25T and its remotely piloted counterpart the RCA-25T; the 1-inch Series-4 remote pilot type is the RCAC25T4, published with the K2546 kit; the tank-mounted equivalents run from the CA-25MM to the CA-76MM; and the flanged 1-inch inlet version is the RCAC25FS with kit K2512.

The published equivalent table: T series and MM series

The site publishes the two families that cover most installed bases in one table, and it is the fastest way to convert an old marking into a current orderable valve. In the T series the orifice, port size, diaphragm layers and flow figures move together: the CA/RCA 25T is a 1-inch valve published at KV/CV 20/23, and the 35T raises the port to 1¼ inches and the flow to 36/42.

The MM series follows the same logic with different numbers, because the manifold-mounted geometry flows differently: the CA/RCA 25MM is published at 26.24/30.62 and the 76MM at 165.84/193.54.

The five parameters that cannot change

Orifice and flow. The orifice number is the internal passage size, and the KV/CV figures are the published flow behaviour. A replacement with the same port size but a smaller orifice opens more slowly and passes less air per pulse, which changes how long the venturi takes to develop and how much air each cycle consumes.

Pilot architecture. An integral pilot valve cannot be replaced with a remote pilot body without also providing a pilot valve, a pilot box and its control wiring. The reverse is easier: a remote pilot valve is more flexible to wire, but it needs the pilot chain the original did not have.

Coil voltage and connector. The published valves are offered at AC220V and DC24V, with a 230VAC version and an IP65 marking on some CA and RCA pages, and the connector follows the DIN 43650A pattern. A mismatch does not damage the valve; it stops it firing, and it fails in a way that looks exactly like a failed diaphragm.

Diaphragm and seal material against temperature. The published temperature ranges are why this is not a detail: nitrile is published for −40 to 120 °C and Viton for −29 to 232 °C. Where the gas is hot, the material decides whether the valve survives a season, and it changes the valve and the spare kits you hold.

Pressure and air quality. The published working range is 0.3 to 0.8 MPa with clean air as the medium, at −5 to 55 °C ambient and 85 % relative humidity. If your header sits outside that band, the valve is the wrong part for the position however well the name matches.

A diaphragm kit or a whole valve, and what the published data says about the failed one

Most replacements are not of the whole valve. The published CA programme is built around the diaphragm repair kits, listed by the valve they serve: K2501 in nitrile for the CA-25T and RCA-25T, K2503 in Viton for the CA-25T and the CA-25DD, K2530 for the flanged types, K2000 and K2007 for the 3/4-inch valves, and K2546 with the AG8113901 and K2551 references for the Goyen Series-4.

The same logic runs through the wider range, with Pentair CA35T and CA50T kits, a CA-62T kit in Viton, the CA-76MM NBR kit and a 3½-inch CA102MM kit in nitrile. For an OEM that list argues for stocking kits rather than complete valves: the diaphragm is the wearing part, the body and armature are not.

What the published data says about why a valve fails is mostly about conditions rather than the valve. Diaphragm and seal material is chosen against a temperature range, the air has to be clean and dry, the published inspection interval for kits and pilots is annual, and the published diaphragm life figure is one million cycles. A valve sitting in a wet header, or holding a hot and dirty medium, is not a manufacturing defect.

The published statement that a diaphragm valve is not a structural component and should not be relied on to retain tanks or pipes belongs in a replacement note: it is a statement about what the valve can carry, and the reason a replacement should never be settled by appearance alone.

The warranty position is published too: 1.5 years on pulse valves, with a replacement supplied without extra charge including shipping when a valve is found defective and returned. That covers a defective part, not one ordered with the wrong orifice for the position, which is why the five parameters above come first.

What changes on the tank when the valve is changed

The site publishes its own installation sequence, and it reads like a commissioning note rather than marketing copy. Prepare the supply and blow tube pipes to suit the valve specification, and do not install valves underneath the tank. Make sure the air source is clean and dry, and keep the tank and pipes free of dirt, rust and particulate.

Two lines in that sequence cause the failures people later blame on the valve. When mounting the valve to the inlet pipe and the outlet to the baghouse, make sure no excess thread sealant can enter the valve itself and keep it clear in the valve and pipe, because this is critical to its working. Then apply moderate pressure and check for installation leaks before fully pressurising.

On the pneumatic side, the general rules for compressed air systems are set out in ISO 4414, and the purity of the air you deliver is graded in ISO 8573-1. Where a tank is new or has been opened, specifying the air quality you deliver is cheaper than diagnosing a valve that closes slowly.

On the electrical side, the solenoid and controller arrangement falls under the general requirements for the electrical equipment of machines in IEC 60204-1, the risk assessment for the installation is the subject of ISO 12100, and the working pressure is a pressure-test question, for which ISO 5208 sets out how industrial valves are tested.

The spares you will order again

A pulse valve is rarely a one-off purchase. The site publishes a supporting programme around the valves: solenoid coils, pilot valves, single-head and double-head bulkhead connectors, timers, and the DMK-3CS-6 pulse valve controller for baghouse filter control.

The repair kits have their own families, and the catalogue is organised by the valve a kit belongs to rather than by the material, which is the more useful way to buy them: K2501 and K2503 for the 1-inch CA-25T and CA-25DD valves, K2530 for the flanged types, K2016 for the 3/4-inch nitrile position, K2017 and K2106 for the RCAC20T3 pattern, K2003 and M1174 for the nitrile kits, and K2546 with K2551 for the Goyen Series-4.

Customer-made parts are accepted from a drawing or sample, and imported diaphragm kits can be supplied where a buyer wants a higher-grade option. For an OEM that means a machine parts list can be built from one supplier instead of four, and the same list becomes the service parts list for the customer.

Who supplies the valve, and what they stand behind

The company behind the site is Green Power Co., Ltd., founded in 2005, with its factory in Pukou Industrial Zone, Shengzhou, Zhejiang, two hours by car from Shanghai and about 80 kilometres from Ningbo Lishe and Hangzhou Xiaoshan international airports. It describes itself as a factory specialised in pulse valves and diaphragm kits, and the range runs from valves and membrane kits to coils, pilots, bulkhead connectors, timers and intensified filter membrane.

Two published commitments matter most. Every valve is pulse tested with pressure air before it leaves the factory, and the 1.5-year warranty replaces a defective valve without extra charge including shipping once the defective unit is received. The site also states that quality is controlled to ISO standards, with producing and testing equipment and a quality management system behind it, and that customs paperwork such as FORM E and certificates of origin is available.

The published supply ability is 10,000 pieces per month from Ningbo and Shanghai, under a stated policy of on-time delivery and steady quality. For a baghouse OEM that matters less than spare parts continuity: will the same kit number still be there three years later? A supplier that publishes part numbers is easier to hold to than one selling on description, and the quality system side of that question is what ISO 9001 asks any supplier to be able to evidence.
