UPVC ANGLE SEAT VALVE

UPVC ANGLE SEAT VALVE

UPVC Angle Seat Valve Supplier in India, that are activated backwards can prevent fluid pressure. It is suitable for high-flow work and is installed in lines where the conventional ball and other irrigation valves are difficult to assemble and use.

This is a pneumatically-operated, piston-actuated valve with a piston actuator that acts linearly to pull a seal out of its seat. Unseated, the seat is placed at an angle to allow for maximal circulation. Hot temperatures and big flow rates, such as steam or water; make angle seat piston valves a good choice.

Installed horizontally or vertically, it’s flexible. When utilised in an underground valve box, it is exceedingly simple to access and wash after a time of use. Easy operation of UPVC Angle Seat Valve manufacturer & exporter in India. It is made possible by a smooth throttling wheel. A fully closed valve will have zero leaking within the operating pressure limit. Design-wise, it’s robust and durable. There is no water hammering when it is turned on.

The VV angle seat valve is a shutting-off and regulating valve particularly suitable for clean fluids.

• Connection system for solvent weld, threaded and flanged joints
• Can be installed in any position
• No metal parts in contact with the fluid
• Valve material compatibility (PVC-U) with water, drinking water and other
food substance conveyance according to current regulations
• Can be maintained with the valve body installed

ANGLE SEAT VALVE

PRESSURE VARIATION ACCORDING TO TEMPERATURE

For water and non-hazardous fluids with regard to which the material is classified as CHEMICALLY RESIS-TANT. In other cases, a reduction of the nominal pressure PN is required(25 years with safety factor).


PRESSURE DROP GRAPH


KV 100 FLOW COEFFICIENT

The Kv 100 flow coefficient is the Q flow rate of litres per minute of water at a temperature of 20°C that will generate Δp= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely
open.

RELATIVE FLOW COEFFICIENT GRAPH

The relative flow coefficient is the flow rate through the valve as a function of the degree of valve opening. Horizontal axis: Percentage opening of the valve Vertical axis: Relative flow coeffi- cient
