BALANCED 2-WAY/2-POSITIONALVES FOR THROTTLING SERVICE
FOR WATER, H.W.C.F., OIL OR OTHER LIQUIDS
The Valv-Trol 3-Position 2-way Valve (Throttle Type) is basically our
standard Balanced 2-Way Valve (Bulletin A-5) with a double diaphragm top
assembly. The lower diaphragm, which is actuated by applying air to port “A”
,will stroke the valve completely. This operation is the same as a standard 2-
way valve
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.
The upper diaphragm is actuated by applying air to port “B”. This will stroke the valve anywhere from 10% to 90% of full stroke depending on the setting of the
nuts on the adjusting stem
With this valve, you have a choice of full flow, restricted flow, or no flow. The
selection depends on which diaphragm is actuated. This feature is often used
to slow the ram on a hydraulic press just before the press closes completely or
when it starts to opent before the press closes completely or when it starts to open.
The intermediate position is determined by the setting of the
adjusting nuts on top of the valve
Proven to be very resistant to the effects of corrosion, wear, and wire drawing
for longer service life.
Can be field converted from Normally Open (NO) to Normally
Closed (NC) or vice versa.

assembled normally open (N.O.) or normally closed (N.C.). Double diaphragm
assembly may also be added to some 4” valves.
The Valv-Trol Advantage .
Many parts of Valv-Trol Valves are interchangeable between the same size 2-way, 3-way, and check valves. This helps you to reduce your spare parts inventory and allows us to maintain a more complete inventory for your emergency availability and shorter lead times

Our valves are all subjected to 100% pressure testing to ensure a drop
tight seal before we ship to our customers.
