Check Valves

The Check Valve permits the air flow in one direction but checks the flow in the opposite direction, thus keeping the output pressure at a constant level. The Check Valve can keep the service pressure at-750mmHg (vacuum) and permits piping under low pressure.

• Back Flow Prevention, keeps pressure in outlet side
• Ideal for vacuum retention or low-pressure application
• Body of in-line type is made of aluminum
• Low-cost and Lightweight Resin Type available
