Spring operated, air operated & differential pressure regulators
also known as pressure reducing valves or forward pressure regulators
Uses of these versatile regulators...
• Prevent overpressure conditions to downstream equipment such as filters, sensitive tools, etc.
• Convert excessive or wildly fluctuating upstream pressure to a constant predetermined downstream pressure.
• Control pressure differential (Delta P) across downstream system equipment (Refer to Series PRD below).
• Regulate to the correct pressure range so that a flow system or piece of equipment can operate safely and
effectively.
These valves have many outstanding features...
• Offer wide range of pressure settings with smooth, sensitive operation.
• Engineered thermoplastics for corrosive and ultra pure liquids.
• One piece body construction eliminates internal leakage that can cause malfunction.
• Pressure sensing is done with rolling diaphragms. These have the largest surface area among all diaphragm
regulator designs, which results in the greatest accuracy. Furthermore, the sensing chamber is isolated from
the flow path, so it provides unrestricted flow.
• Each valve is individually tested prior to shipment.
• No wetted metals; all external fasteners are stainless steel, control springs on spring loaded models are not in
the liquid.
• Maintenance-free designs.
• Factory pre-set if requested.
• Internal sensing area flush option
