Compressor discharge is high pressure, pulsating, and unforgiving. The DFT Excalibur closes before flow reversal occurs, provides tight shutoff, and is built for a million-cycle service life in severe service applications.

Gravity-dependent check valves struggle in vertical flow-down installations. DFT in-line check valves are rated for any orientation, horizontal, vertical up, or vertical down, with consistent spring-assisted closure in every position.
#CheckValves #PipingDesign
Gas transmission exposes check valves to pulsating compressor discharge, pressure swings, and corrosive gas compositions. DFT check valves are engineered for the specific demands of these applications, not adapted from general-purpose designs.
#GasTransmission #CheckValves
Standard check valves aren't built for reciprocating compressor discharge. Each stroke creates a momentary flow drop that accelerates seat wear. The DFT PDC's pulse damping chamber holds the disc open through every cycle.

Water hammer generates pressure spikes up to 10x normal system pressure. Check valve type is often a direct cause. Spring-assisted valves close before flow reversal — stopping the shockwave at the source.

Compressor systems are sensitive to pressure changes during flow transitions.
Valves that rely on reverse flow to close can introduce vibration and stress.
DFT spring-assisted check valves close earlier, helping stabilize compressor systems.
#CompressorSystems #FlowControl
Flow path design impacts system performance.
Axial-flow check valves align with flow direction, helping reduce turbulence and support stable pressure.
DFT check valves can be installed in vertical flow up and vertical flow down orientation.
#AxialFlow #FlowControl
Pump shutdown doesn’t stop flow instantly. As velocity decays, pressure transients can create vibration and stress.
Delayed valve closure allows reverse flow and stronger pressure spikes. DFT check valves respond earlier to help stabilize system performance.
#FlowControl
Reverse flow can begin within milliseconds after pump shutdown.
If a check valve closes too slowly, returning fluid can cause slaming, vibration and pressure spikes. Spring-assisted valves respond quickly, helping stabilize pump discharge systems and protect piping.
Remembering and honoring those who gave their lives in service.
Their sacrifice is not forgotten.
#MemorialDay #HonorAndRemember
In fluctuating flow conditions, waiting for reverse flow to close a valve can lead to instability.
DFT’s spring-assisted check valves begin closing as flow decreases, helping reduce slam and stabilize pressure.
#NonSlamValves #FlowControl #CompressorSystems
Check valve performance goes beyond line size and pressure rating. Closure behavior, pressure dynamics, and installation affect system stability. At DFT, we apply these system‑level factors to check valve selection and sizing for real operating conditions.
#CheckValves
Reverse flow can begin almost immediately as pump flow decays.
Delayed closure may lead to pressure spikes and vibration.
DFT check valves are designed to respond earlier, helping reduce the impact of reverse flow events.
#FlowControl #CheckValves #PumpSystems
Upfront cost doesn’t tell the full story.
DFT engineered check valves help reduce maintenance, extend service life, and limit unplanned shutdowns — lowering lifecycle costs and improving long-term system value.
