FEATURES & SPECIFICATIONS
Automatic reduces the higher inlet pressure to a steady lower downstream pressure, regardless of fluctuating demand or varying upstream pressure.
The low flow by-pass lets a small amount of fluid pass through to keep the pressure steady when demand is low. This stop the valve from constantly turning on and off.
Pilot-operated regulator capable of holding downstream pressure to a pre-determined limit. The main valve and pilot valve will close when the downstream pressure exceeds the setting of the control pilot.
Full bore globe pattern design for superior control characteristic.
Nylon reinforced diaphragm for long-lasting performance.
Durable fusion bonded epoxy coated.
Design comply with EN 1074-5.
Flange drilled to EN 1092-2 PN16 / ANSI Class 150 (Specify on order).
Working pressure : 16bar.
Shell test pressure (x1.5) : 24bar.
Seat test pressure (x1.1) : 17.6bar.
Working temperature : -20°C … 110°C (EPDM) / -10°C … 80°C (NBR).
Suitable Media : Water.
Setting Range : 1 … 12bar.
