• EPDM seal and O-ring
• Size:2″-10″
• Operating temperature range: 41ºF to 122ºF
• Pressure Rating for 1/2″ – 2″ valves: 200 psi @ 70ºF
• Pressure Rating for 2-1/2″ – 4″: 150 PSI @ 70ºF

Gear Operated Butterfly Valve opens and closes the valve by manually rotating the turbine to drive the valve plate around its axis.

Advantages
1、Simple structure, small size, small volume, lightweight, easy to install, suitable for large diameter valves.
2、Easy to open and close quickly, labor-saving, small fluid resistance, can often be operated.
3、Good sealing can be achieved under low pressure.
4、Good adjustment performance.
5、The effective circulation area of the valve seat channel is larger when fully open, and the fluid resistance is smaller.
6、The opening and closing torque are minimal and the operation is flexible and effortless.
7、Sealing surface materials are generally rubber and plastic, so the low pressure sealing performance is good.

Disadvantages
1、Small operating pressure and temperature range.
2、The sealing is poor.

3、The installation needs to be mounted on the pipe together with the flange.
