DC Series Check Valves
are Rugged, Cost-competitive
The DC Series offers basic, workhorse check valves –
ruggedly built, readily available and reasonably priced.
They are in-line valves, available in sizes 1/4" to 2",
with a pressure rating range up to 5000 psi, and
flow capacities to 300 GPM.
DC Series
Features
1.
All-steel construction–no internal seals or gaskets to
wear out.
2.
One-piece body eliminates threads and seals that may
be potential failure or leakage points.
3.
Valve seats resist damage from shocks, surges and con-
tamination.
4.
Poppet has an oil retention groove that lubricates the
bore and eliminates galling.
5.
Poppet spring is isolated from the liquid flow stream,
minimizing turbulence.
6.
Poppet is heat treated to help prevent damage from
shocks, surges and galling.
7.
Close tolerance fit between poppet and poppet retainer
creates a cushion that protects valve from surge shock
damage.
8.
Check valve body is shaped like an arrow to indicate flow
direction.
9.
Available in a variety of standard and non-standard
crack pressures.
