A normally closed two-stage diaphragm preset valve for use with electronic relay control. Stainless steel or brass pilot valves are available. Dimensionally interchangeable with the 650 Hydraulic Preset Valves.
Size: 1-1/2″, & 2″ Type: SP, SPA, SS & SSD Pressure: 150 PSI (10.5 BAR) Temperature: -40F to 160F (-40C to 71C) Flow Capacity: Up to 200 GPM Viscosity: 2800 SSU (580 cPs) Body Material: Aluminum or Stainless Steel Solenoid Material: Brass or Stainless Steel Seals: FKM Voltage: 12 or 24 VDC; 110 or 240 VAC
The air check valve operates on differential pressure, closing when air is present. Designed to increase air eliminator efficiency during product depletion.
757 Differential Pressure Valve
The diaphragm differential pressure control valve has a normally closed, spring loaded design. Provides a constant 15 PSI differential pressure and controls flow when vapor is sensed. Security and 2-stage solenoid valves are available upon req [...]
750 Hydraulic Preset Valve
A normally closed, hydraulically balanced piston control valve allows for auto-batch preset deliveries. The right angle, two–stage control valve is mechanically linked to Veeder Root Preset Counter.
