Engineering Overview of Goyen Valves: Pulse, Diaphragm, and Solenoid Solutions
GOYEN valves, developed by Emerson's engineering division, are an industry standard in the segment of pulse and control valves for industrial aspiration and pneumatic systems. The design, optimized for high-intensity operation, guarantees a service life exceeding one million actuation cycles. EV Group China engineers integrate these valves into bag and cartridge filters, gas cleaning installations in the energy sector, as well as into dust removal systems in metallurgical and chemical industries.
Technical Analysis of Goyen Pulse Valves
Goyen Pulse Valves are precision diaphragm devices designed to generate a powerful, short pulse of compressed air. Their key function is to regenerate filtering elements (bags, cartridges) by means of reverse pulse cleaning.
The design includes a cast body with a threaded or flanged connection type, a high-strength elastomer diaphragm, and a control module (solenoid pilot or port for external pneumatic control). Pilot activation causes a sharp pressure drop in the control chamber, leading to the instantaneous opening of the main flow area and the formation of a shock wave for cleaning.
Nomenclature of Goyen pulse valves by size:
- RCA10T: Compact 3/8'' design for local and small-sized aspiration units.
- CA/RCA20T, CAC/RCAC20T: Universal 3/4'' models for standard industrial filters.
- CA/RCA25T, CAC/RCAC25T: The most in-demand 1'' design for a wide range of tasks.
- CA/RCA32T: 1 1/2'' modification with increased flow coefficient (Kv) for more productive systems.
- CA/RCA35T, CA/RCA40T, CA/RCA45T, CA/RCA50T: Series for large-sized filters (1 1/4'' – 2'') requiring a large volume of purge air.
- CA/RCA62T, CA/RCA76T: Flagship high-performance 2 1/2'' and 3'' valves, designed for the most powerful gas cleaning systems.
Goyen Solenoid Valves: Classification and Applications
Electromagnetic (solenoid) Goyen valves are designed for precise dosing and shut-off of liquid and gaseous media flows. Their operation is based on the creation of an electromagnetic field by a solenoid, which moves a plunger (core) that controls the main shut-off element directly or through a pilot channel.
Engineering classification by operating principle:
- Direct Acting Valves: 2- and 3-way configurations, actuated without a minimum pressure differential (from 0 bar). Ideal for systems with low pressure and flow, as well as for vacuum applications.
- Pilot Operated Valves: Require a minimum pressure differential for actuation. Designed to control high-pressure and high-flow pipelines, which is standard for industrial system mains.
Design Options for Goyen Diaphragm Valves
Goyen diaphragm valves are designed to provide maximum actuation speed and high compressed air flow. Classification by mounting connection type determines the valve series:
- T Series (Threaded): Models with internal threaded ports (BSP or NPT) for standard pipe mounting.
- DD Series (Dresser Nut): Equipped with compression fittings (union nuts) for quick and easy mounting on smooth pipes without threading.
- FS Series (Flanged): Flanged connection for critical assemblies where increased reliability and vibration resistance of the connection are required.
- MM, MR Series: Valves for mounting on a flat manifold, allowing the creation of compact valve blocks.
- 400 and 500G Series: Integrated solutions where the valve is part of the blow tube design.

FAQ: Technical Questions about Goyen Valves
What is the difference between CA and RCA series?
CA series are valves with an integrated solenoid pilot (electromagnetic coil). RCA series are valves with a port for external pneumatic control, without a solenoid.
What are Goyen controllers?
These are a line of electronic controllers (timers) that manage the purge cycle. They allow programming the duration and interval of pulses for a group of valves, optimizing compressed air consumption and the cleaning efficiency of filters.
What is the purpose of a valve with the marking RCAC25FS?
This is a flanged model (FS) of 1'' size with external pneumatic control (RCA) and a cast aluminum body (C). It is designed for mounting on systems subject to strong vibrations or requiring maximum connection reliability.
