Worm gear worm gear transmission stainless steel lined fluoropolymer flange ball valve
Worm gear stainless steel lined fluorine flange ball valve
This product adopts a worm gear reduction mechanism, flange connection, and lined ball valve structure. The current page diameter is DN50-DN1000, pressure is PN10/PN16, and material fields are 304 and PFA/FEP lining. The current model field should maintain its original value, and the specific model and lining suffix should be confirmed in the official product information and order.
What occasions is worm gear transmission suitable for?
For ball valves with larger diameters or higher opening and closing torque, the worm gear mechanism can reduce manual operating force and provide deceleration transmission. The actual operating torque, reduction ratio, and handwheel size need to be determined according to the specific valve.
How to choose between PFA and FEP?
The current parameter fields are PFA and FEP, which should be selected based on the composition, concentration, temperature, and pressure of the medium. The main text will no longer extend 316L or PTFE as default configurations.
Is fluoropolymer-lined ball valve suitable for strongly corrosive media?
It is necessary to judge based on the compatibility between the specific chemical medium and the lining material, and "strong acid and strong alkali are all applicable" cannot be used as a unified conclusion.

Frequently Asked Questions
This worm gear lined fluorine ball valve requires a 316L valve body. Can I place an order directly according to the original specifications?
No. The current existing valve body adopts the 304 scheme; When 316L is needed, corresponding configuration information should be obtained separately, and the liquid receiving parts and ordering conditions should be checked. 304 cannot be directly changed to 316L for supply.
Can we replace PFA/FEP with PTFE for this worm gear lined fluorine ball valve?
Cannot be replaced without verification. Re confirm according to the medium, temperature, pressure, and structural data; The existing PFA/FEP option cannot automatically add PTFE configuration.
Can worm gear ball valves be used for precise flow regulation?
The worm gear mechanism mainly solves the problems of manual transmission and torque, and whether it is suitable for continuous adjustment still depends on the characteristics of the ball core, valve seat, and flow rate.
