SPECIFICATIONS

Pro 7900 Series 1" Valves

The solenoid actuated remote control valve shall be of normally closed design. Inlet and outlet connections shall be 1" female NPSF. Body configuration shall be straight-through globe (angle) style. The valve shall operate at pressures from 10 to 150 PSI with fluid temperatures up to 125 degrees F.

The valve body and bonnet shall be constructed of glass reinforced nylon. The bonnet shall be bayonet-mount design so that the bonnet; diaphragm and solenoid can be removed in one assembly without removing bolts from the body. Bolts will be con­structed of stainless steel.

The fabric-reinforced diaphragm shall be of one piece molded construction. The diaphragm shall remain captured to the bonnet when the bonnet is removed.

A hand-actuated internal bleed shall vent water to downstream piping. A hand-actuated flow control (Models 7911 and 7931) knob shall reduce water flow from full open to close in less than three complete turns.

The solenoid shall be removable from the body in one assembly that captures the solenoid plunger; spring and bleed ring. The one piece solenoid shall be fully encapsulated and draw 0.50 amps inrush and 0.23 amps holding current. The solenoid plunger and attached spring shall be constructed of stainless steel.
