Silent Check Valves

Model: Full Line

The Manufacturer Standardization Society (MSS) developed the MSS SP-126 standard to fulfill the industry need covering a unique class of check valves. These in-line (no bonnet), spring assisted, centre guided check valves are termed “silent check valves” because they reduce the potential for water hammer.

Advantages Over Other Check Valves:

  • Sized to your flow conditions, not the line size
  • Non-slam, spring assisted
  • Prevents reverse flow and water hammer
  • Designed to handle pulsating, reciprocating service
  • Easy to repair with replaceable parts
  • Multi-positional installation
  • Soft seating available, for tight shut-off

 Oil & Gas Applications:

  • Pump discharge (water, glycol, amine)
  • Compressor discharge (gas, air)
  • Water / C02 injection and disposal
  • Boiler feed water
  • Cryogenic – Deep Cuts
  • Sour gas flow line and well heads
  • Oil and gas metering
  • Headers and bypass lines
  • Rotary selector valves
  • Casing gas vents
  • Vacuum service
  • Back pressure applications
