Hydraulic Control Pressure Reducing Valves DN100 PN16 With Double Gauge

Hydraulic Control Pressure Redusing Valve DN100 PN16 With Double Gauge

Brief introduction:

Streamlined body, combined floating-ball disc with cone-shape sealing surface,

these insure no abnormal vibration and noise when the valve is in use.

These can also reduce pressure loss, makes the scope of upstream pressure much wider than other pressure valves and pressure output more stable.

Widely used in potable water supply, building construction and so on.

Features:

⊙  Unique design

Streamlined body. Combined floating-ball valve clack. Cone-shape sealing surface.

Diaphragm type control. Filter installed at the pipe system.

Screw hole at the bottom can clear the sediment.

⊙  Excellent proof corrosion characteristics

Internal and external epoxy resin coating. Floating-ball and filter are both made of bronze.

⊙  Reliable hygiene principles

Epoxy resin and rubber comply with hygiene standard. Sealing material are made of rubber and PTFE. Trims are made of stainless steel or bronze.

The valves limits the flow rate in the pipeline to a preset rate, regardless of upstream pressure variations.

The valves is controlled by pilot valves, which takes use of integrated orifice plate to detect flow rate

represented by differential pressure, and the differential pressure is used to control the pilot valves to

implement flow rate control.
