The Piper

• Since the PRV is Diaphragm operated it has better pressure control ,less noise and maintenance compared to the older piston operated PRVs.

• More over Diaphragm is thin walled , corrugation shaped for better flexibility & smoother operation. Increased surface area of diaphragm reduces overall size of PRV. i.e. compactness.
• Compact and light weight.
• Nylon reinforced NBR Diaphragm for better strength and longer life.
• ‘Cartridge’ design internals - entire working mechanism is in a cartridge which operates independent of the body. Thus, servicing is without removing body from pipeline.
• In-built provision for inserting pressure gauge.

• The W21 has a unique inclined seat arrangement which gives more flow capacity as compared to other household PRVS.

• Diaphragm operated gives better life and pressure sensitivity compared to piston operated.
• Built-in filter bocks dirt/scale particles up to 200 microns thus preventing malfunction and pressurization damage.
• This 2-in-1 product not only reduces pressure but also acts as a fine filter which helps in the unclogging of showers, aerators in the bathroom.
• Corrugate shaped diaphragm with nylon reinforcement for enhanced flexibility and longer life.
• Low weight internals for quick response to changes in the flow/pressure improves performance like never before.

Applications :

Pressure Reducing Valves protect household water installations for industrial or commercial applications within the range of their specification. By installing a pressure reducing valve, pressurization damage is avoided and water consumption is reduced. The set pressure is also maintained constant even when there is wide inlet pressure fluctuation. Reduction of the operating pressure and maintaining it at a constant level minimizes flow noise in the installation.

Salient Features:

• Diaphragm operated gives better life and pressure sensitivity compared to piston operated.
• Built-in filter bocks dirt/scale particles up to 400 microns thus preventing malfunction and pressurization damage.
• Transparent filter-cap gives visual indication of all the trapped dirt thus indicating when the next cleaning is required.
• Corrugate shaped diaphragm with nylon reinforcement for enhanced flexibility and longer life.
• Low weight internals for quick response to changes in the flow/pressure improves performance like never before.
