Plastic Butterfly And Ball Valves With Actuator

---

ude supply Plastic Butterfly Valves which are made from light quality thermoplastic like PP, HDPE-High density Polyethylene and PVDF - Polyvinylidene Fluoride. The valves are tight shut off in both flow directions and recommended for pressure rating of PN10. These valves offer square section shaft that provide positive engagement between shaft and disc and shaft & lever ensuring positive shut off with quarter turn operation. They are suitable for flow in either directions or can be utilized either vertically or horizontally. The valve disc fitted with seat ring is easily replaceable as well as economical compare to conventional rubber liner. They are also available with double-flanged end connections. The butterfly valves are available having flange with drilling as per BS, ASA, DIN or any other standard.

Design

Thermoplastic Butterfly valves 2" to 8'' are wafer style to fit between ANSI B16.5 class 150 flanges. Disc is contoured for lowest possible drop (highest CV). Shaft is 410 S.S. and of one piece through shaft design, with square drive through entire length of blade. Seat liners shall be full faced with integral ribbed flanges. No auxiliary gasket shall be required or for installation. Seat liners shall effectively isolate the body and shaft for the flow media. Seat liners shall also thermally insulate the body from the internal operating temperature. Valve liner and seals are replaceable. Materials of construction will be decided based on the process demand.
