Pressure Relief Valves

Important Information regarding Pressure Relief Valve 16C807.

Pressure Relief Valve 16C807 can only be used on the G3 Pump. It is not intended for use with any other products.

The pressure relief valve uses a

a

b

pressure adjustment screw (a) to

 

 

 

set the pressure release point. It

 

 

is not intended as a way to

 

 

relieve pressure during normal

 

 

operation, but as a protective

 

 

measure in the event there is an

 

 

unintended pressure increase in

 

 

the system. Do not use this pres-

 

 

sure relief valve a means of

 

ti15644

relieving pressure in day-to-day,

 

 

 

normal cycle operation.

a = adjustment screw

 

The pressure adjustment screw

b = locking nut

 

 

 

will require periodic adjustments.

 

 

Whenever the valve is set/adjusted (after the set point is found) it is important to ensure that the valve is not bot- tomed out and there is at least 1/2 turn of adjustment remaining. This is determined by turning the screw (a) 1/2 turn and then back turning it out again.

NOTE: Turning adjustment screw (a) clockwise increases pressure.
