PVDF Angle Seat Valve
PVDF Angle Seat Valve is suitable for high-flow work and is installed in lines where conventional ball and other irrigation valves are difficult to assemble and use.
It is a pneumatically operated, piston-actuated valve with a piston actuator that acts linearly to pull the seal out of its seat. With no seat, the seat is placed at an angle to allow maximum circulation. hot temperatures and large flow rates, such as steam or water; Make PVDF Angle Seat Valve is a good choice.
Installed horizontally or vertically, it is flexible. When used in an underground valve box, it is extremely easy to access and wash after a period of use. Easy Operate PVDF Angle Seat Valves Manufacturer and Exporter in India.
This is made possible by a smooth throttling wheel. A fully closed valve will have zero leakage within the operating pressure range. Design-wise, it is strong and durable. The water hammer does not move when it is turned on.

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.

| Kv100 l/min | 47 | 110 | 205 | 375 | 560 | 835 | 1300 |
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
