Balanced 3-Way“ Diaphragm Operated Valve
Specializing in standard and custom high pressure valves for
water hydraulics and other high pressure water systems.
water hydraulics and other high pressure water systems.
TWO-PRESSURE VALVE ASSEMBLY
FOR WATER, 95/5, OIL OR OTHER LIQUIDS
The Valv-Trol Balanced 3-Way Diaphragm Operated Valve is
intended for general industrial use. With its rugged steel diaphragm top and
corrosion resistant body construction, it is ideally suited for hydraulic systems that use either raw water or 95/5. It also works extremely well on oil hydraulic
systems.
Replaceable seats and discs are made of hardened stainless steel.
Proven to be very resistant to the effects of corrosion, wear, and wire drawing for longer service life.
Proven to be very resistant to the effects of corrosion, wear, and wire drawing for longer service life.
Internally, the skirted discs provide a gradual change in the rate
of flow.
Helps reduce the shock of opening or closing. Any foreign matter is flushed from the seats before the final seal is completed..

The valve can be piped either normally open to pressure or
normally closed.
Can also be used to divert flow from one line to another (may require a small internal modification).

EXAMPLES OF VALV-TROL 3-WAY VALVE
APPLICATIONS
Diversion service—For diverting flow from one source to either of two outputs. This service may require a minor internal modification to prevent shutoff of flow during shifting
One circuit for stopping cylinder rod at any point on either extend or retract cycle.
Selector service—For selecting flow from
either of two sources. Applications include any compatible fluids including water, grease,
oil, paint, etc.
on either extend or retract cycle.
Simple single acting, gravity return, hydraulic
press. See Bulletin A-1 for information on
two-pressure valves..
