Single Stage Station
For pressure reductions not exceeding 100 psi* and low load variability.
Let the Experts Design Your Next Steam Pressure Reducing Valve Station.
HYFAB designs and builds steam pressure reducing valve stations. Thoughtfully designed, factory built, tested, and ready to install, backed by 40 years of experience.
Two Stage Series Station
For pressure reductions greater than 100 psi and low load variability. May also serve intermediate pressure loads.
Single Stage Parallel Station
For total pressure reduction not exceeding 100 psi and loads that vary widely due to seasonal changes or process requirements. Uses two PRVs in parallel, typically.
Two Stage Parallel Station
or pressure reduction greater than 100 psi and highly variable loads. Also accommodates intermediate pressure loads, if required.
HYFAB Steam Pressure Reducing Valve Stations Typically Include:
- Cast Iron Regulators
- Pressure Pilots
- Strainers
- Gate Valves for Isolation
- Globe Valve for Bypass
- Inverted Bucket Drip Traps
- Steam Safety Valve
- Drip Pan Elbow
Standard Construction
- Fabricated of ASTM A53, type S (seamless) pipe and nipples.
- All welding is performed by ASME Section IX certified welders.
- Most stations have floor support feet to be supplemented with field support for connecting piping.
- High quality spiral wound gaskets with appropriate fill are used on all flanged connections.
- Every PRV station is pressure tested prior to shipment to ensure leak free operation.
Options
- Special Materials - Ductile iron or cast steel regulators.
- Noise Attenuation – Muffling orifices, sound attenuators, insulation blankets
- Pilots for additional functions – Temperature control, remote shut-off, remotely adjustable setpoint
- Separators – When moisture content is of significant concern.
