Operating Instructions for Lock Release Valve
Use on equipment where steam locking/air binding, which slows the discharge of
condensate and reduces equipment efficiency, tends to occur (cylindrical dryers, air fin
heater, etc.).
1. When the product is shipped from the factory, the element retainer is raised in the
maximum, valve-closed position.
2. Before operating the lock release valve, examine the trap outlet and confirm that the
trap is functioning properly.
3. Operate the lock release valve as follows: (tools required: flat-head screwdriver)
Open Valve - Insert the screwdriver into the slot on the top of the element
retainer and slowly turn clockwise. (Do not turn the element retainer past the
point at which it stops.)
See charts below for steam discharge/air discharge. (Maximums are shown.)
Close Valve - Insert the screwdriver into the slot on the top of the element
retainer and close by turning counterclockwise.
Raise the element retainer until the snap ring contacts the bottom of the gland
case. (Do not turn the element retainer past the point at which it stops.)
4. If steam should leak from the gland retainer nut or gland case, it can be stopped by
further tightening the gland retainer nut.
(Do not over tighten, otherwise element retainer may seize and become
unworkable.)

Needle Valve Unit
Use gloves when operating the needle valve and keep all body parts well clear
of the product.
Failure to do so could result in burns, other injury or damage from the blowing of
small amounts of steam and condensate.
