The high performance gear operated butterfly valve refers to the high performance butterfly valve with a worm gear box, which is connected to the switch handwheel through the worm, and turns the handwheel to control the valve switch.
The main materials are carbon steel and stainless steel. The valve seat, valve stem and valve plate can be customized by customers.

Frequently Asked Questions
How do I check handwheel access on the worm-gear wafer valve?
Send the proposed gearbox orientation and available operating and removal space. Request the selected assembly drawing before finalizing the installation.
Which body, disc and seat combination should I put on the order?
Provide the medium, operating conditions and project material requirements and request the actual wetted-material specification. The body-material alternatives on the page do not define every seat and disc combination.
Can I replace my existing wafer valve using the same flange hardware?
Send the existing flange and fastener details, required size and pipe bore. Confirm face-to-face fit, disc clearance and the required bolting arrangement for the selected valve rather than assuming a direct swap.
