Cash Valve Type FR-6 Industrial Back Pressure Valve

Diaphragm actuated valve designed for either continuous or intermittent operation which provide accurate, repetitive pressure control

Product Features

• Protect against periodic high pressure, control dependably at adjusted pressures and shut tight.
• Maintain a pre-determined pressure on the inlet regardless of variations in pressure at the outlet.
• Unique full ‘floating ring’ seating arrangement provides smooth, even control in response to pressure changes.
• Globe type body with two side inlets and a bottom outlet, suitable for angle or in-line installation.
• Fitted with a closing cap to discourage unauthorized tampering.
• Optional differential pressure control modification enables a constantly held difference between reference and valve inlet pressures.
• Incorporates a diaphragm ring above the diaphragm for higher back pressure ranges.
• Rugged, simple design enables easy on-line maintenance and repair.
