Priming Valves
Hale priming valves open when the priming pump is operated to allow the
air to escape from the pump. Two priming valves are offered:
❑ Hale Semi-Automatic Priming Valve (SPVR), for Remote Mounting
A single push button on the operator’s panel starts the priming pump
motor. When a vacuum is created, the SPVR OPENS. (See Figure 2a-
9: “SPVR Priming Valves.”)
Releasing the push button stops the priming pump and the SPVR
CLOSES.

❑ The Hale PVG Priming Valve
The PVG is a combination valve and switch and is mounted on the pump
operator’s panel. (See Figure 2a-10: “PVG Priming Valves.”)
Pulling the handle out OPENS the valve and energizes the primer motor.
Pushing the handle in de-energizes the motor and CLOSES the valve.
