CAUTION:
Foot operated valves must be protected against inadvertent
operation that can cause serious bodily injury.Use of a pedal
guard (PS2043P) is strongly recommended, as it will reduce
the likelihood of inadvertent operation.If this is not suitable in
your application, utilize equivalent protection.
Valve Operation:
These valves will operate mounted in any position.
Valves can be operated either Normally Closed to pressure or Normally
Open to pressure.
In the normal position of the stem (spring returned), Port “A” is
blocked and Port“O” is connected to Port “B”.When actuated by the
foot, Port “A” is connected to Port “O” and Port “B”is blocked.When
the non-locking foot pedal is released, the spring returns the stem to
its normal position.In the locking model, the operator must release
the locking pedal to return the stem to its original (normal) position.
Connect inlet to Port “A”for normally closed valve.Port“B” is exhaust.
Connect inlet to Port“B”for normally open valve.Port“A” is exhaust.
Plug exhaust port for 2-way operation.

Installation & Operating Instructions
Valve should be installed with reasonable accessibility for service
whenever possible - repair service kits are available. Keep pipe or
tubing lengths to a minimum with inside clean and free of dirt and
chips.Pipe joint compound should be used sparingly and applied only
to the male pipe - never into the female port.Do not use PTFE tape to
seal pipe joints - pieces have a tendency to break off and lodge inside
the unit, possibly causing malfunction.
Filtered and lubricated air is necessary for maximum valve life and
minimum maintenance.
Factory Pre-Lubrication - All valves are pre-lubricated at assembly
with a petroleum based grease.
