Wrench length for butterfly valve
Wrench length for butterfly valve
(OP)
Dear Friends,
Please advise how can we determine the length of wrench for wrench operated butterfly valve 4 & 6 inches. It is class 150, short wafer, flangeless butterfly valve. Is there any standard which specifies the length of the wrench.

I don't really follow your issue. You asked the vendor for wrench actuator and he's supplied on. It's a bit long which is why they normally come as gear operated at this size.
The valve data sheet should supply all the information you need.

From my view,
1. you ask the torque from the manufacturer. They will give you easily.
2. you give the torque and wrench length information to your end user and let them decide whether they are acceptable.
3. If yes, use wrench. If no, use gear box. Of coz, it will be somehow more expansive to use gear box. But for safety and easy use, it worth.
