Plast-O-Matic Series PS High Flow Pilot Operated Valves with PTFE Bellows

Features

• Normally closed, in-line design with bubble-tight shut-off.

• Minimum 5 PSI differential required.

• High pressure: Particularly for applications where high back pressures(up to 70 PSI) are required e.g. controlling flow spray nozzles, high pressure chemical injections, etc. Inlet pressure to 140 PSI.

• High flow rates – Cv’s from 5.2 on the 1/2" size to 80 on the 3" size.

• Unique Design: PTFE Bellows barrier-type dynamic seal prevents leaking of fugitive emissions to the atmosphere.

• Safety/Dependability: Patented Fail-Dry® safety design feature provides advance visual warning if seal malfunctions, while permitting valves to continue operating until maintenance can be scheduled.

• Tested to over 1,000,000 cycles in laboratory conditions, with water.

• Versatility: Can be used with all types of solutions including acids, caustics, solvents and chlorine solutions.

• Rugged thermoplastic construction is resistant to both internal and atmospheric corrosion. No metal parts in wetted areas.

• Positive valve closure in the event of electrical failure.

• Energy-efficient 11 watt coil.

• Molded coil and standard DIN connector; designed to meet NEMA 4X.

• Sizes: 1/2", 3/4", 1", 11/2", 2 and 3".
