Poppet Valves
Best suited for low differential pressures and slower speed compressors, our Poppet Valves are high lift valves with low-pressure drop across the sealing elements. Each valve is custom designed to match your needs and adaptable to existing plug style unloaders or new systems.
Features
- Available in single deck, deck-and-a-half, and double-deck configurations
- Smooth, streamlined flow through the seat for maximum efficiency
- Effectively used where debris or liquid are present
- Low valve losses
- Standardization of poppet design and part numbers allows a reduction in component inventory (same poppet can be stocked for multiple stages of valves)
- Low risk of valve performance loss: generally, failure of a single poppet element is not as critical as with other valve types (concentric rings, ported plates)
- Custom spring design for each application to optimize opening and closing times
- Easily maintained and reconditioned
- Suitable for:
- Both lubricated and non-lubricated compressors
- Sour gas applications
- Compressor speed up to 500 RPM
Specifications
- Poppet sealing elements in PEEK and Nylon material
- Seats and guards are offered in Ductile Iron and 4140 alloy steel for standard valves and in 17-4 stainless steel for corrosive applications
- Springs are offered in chrome silicon and Hastelloy C materials
- Capable of operating across a wide range of parameters, including:
- temperatures up to 390°F/200°C
- pressures up to 2,500 psi/170 bar
