High performance wafer type cut off butterfly valve

High performance wafer type cut off butterfly valve

SD943H electric telescopic butterfly valve（description）Long service life features，valve size：

This series of high performance wafer butterfly valves uses a variety of construction materials, including HACE compliant and abrasion resistant. In addition, after special treatment, the valve can also be used for chlorine gas, oxygen, high vacuum and abrasive media conditions.

Main feature

1,Novel design, reasonable, unique structure, light weight, easy operation, quick opening and closing;

Single PTFE valve seat design, good elasticity, high reliability

1)Don’t add O-rings or metal parts to maintain the seal

2) Long service life, small maintenance,

3) Lip edge sealing structure, can compensate for temperature and pressure changes

4) Sealing test, two-way to achieve no bubble leakage

New XTREME seal material seats

This sealing material enables longer seat life, better performance, and wider use.

Offset shaft and eccentric disc design

• The valve seat does not touch the butterfly plate when it is open and in the middle position
• No wear points in the upper and lower parts of the seat
• Low torque, electro-pneumatic manual operation mechanism requirements are small, high credit price ratio

Fire resisting construction

Fire-resistant valves are fire-tested in accordance with API607, Version 4 and BS6755

A fastening ring is installed at the top of the shaft to prevent the upper part of the shaft from escaping the gland in the event of an accidental shaft break

The seat is easy to maintain

Simply REMOVE THE insert TO REPLACE the seat. Do NOT remove the DISC and shaft

Both disconnection and control

• It has good control characteristics
• Proportional change of flow characteristic curve
• Wide range of adjustment
• The control system can still be sealed reliably
• Single flange butterfly valve in the whole pressure temperature range of either end can be used for pipeline terminal

Complete sets of supply, unified responsibility

• The valve drive device and accessories can be installed and provided in a unified manner
• can be matched with electric device, worm gear device, double action pneumatic device and spring return single action pneumatic device, to use a variety of accessories, including limit device, solenoid valve and positioner.
• OEM on line services

Pneumatic high performance butterfly valve to provide a variety of materials
