ACCESSORIES for Vacuum Priming Systems

PRIMING VALVES

Our standard float operated air release valves have been specifically designed for priming applications.

They include a durable fusion bonded epoxy coating on the inside and outside of the valve body to provide exceptional abrasion and chemical resistance.

The internal trim is 316 Stainless Steel to provide long life, even in aggressive water.

The long body design and skirted float eliminate leakage caused by high vacuum levels.

A weatherproof SPDT water level control switch is normally used to signal when a pump is primed, or to provide a warning if the prime has been lost. An optional DPDT water level control switch is available upon request.

WATER TRAPS

As an optional accessory, an inline water trap can be installed in the main vacuum line to provide additional protection against flooding the priming system. The water trap includes a washable stainless steel filtration screen to protect against large particulates, a float-type check valve for emergency shut off, and a manual drain valve. A liquid filled vacuum gauge is an available option. The clear housing ensures that accumulated water is easily visible. Standard connection sizes are 1/2” NPT to 6” NPT.
