HSCK Combination Stop & Check Valve

These durable, carbon-steel-bodied valves are a
combination stop valve and normally-spring-closed
check valve. Valves open wide for full flow in the
arrow direction on the valve body and promptly reseat
when reverse flow occurs. Stainless steel valve stems
facilitate positive manual closing while Teflon disc
seats assure reliable, long-life seating. Use of these
combination valves reduces pressure drop, minimizes
space requirements, and simplifies installation.

HCK4LR Gravity Drain Check Valve

The HCK4 “LR” series of in-line gravity drain check
valves are dependable, compact, and rugged. The HCK4
“LR” gravity drain check valves feature a low wide-opening pressure differential suitable for liquid transfer
systems and other low-pressure-drop applications. In
addition, an optional, specially-designed adapter allows
direct replacement of existing 3″ and 4″ Wolf-Linde and
H.A. Phillips gravity drain check valves without repiping.

​HCK4 Inline Check Valve

The HCK4 series of dependable, compact, rugged
in-line check valves (disc type non-return valves) is
ideally suited for refrigerant flow control applications.
Valves open wide for flow in the arrow direction on the
valve body. Valves close quickly and reliably when
flow reversals occur.

HCK1 Piston Type Check Valve

These flanged, heavy-duty, piston-type check valves
control the flow of refrigerant. Valves open wide for
flow in the direction of the arrow on the valve body.
Valves close tight when flow reversals occur. The
piston design minimizes pulsations.
