Cast steel lined fluoropolymer worm gear transmission clamp butterfly valve

D371F46 cast steel worm gear lined fluorine butterfly valve

D371F46 adopts worm gear transmission, clamp connection, and fluoropolymer-lined butterfly valve structure. The current page has a diameter of DN40-DN600, pressure of PN16/Class150, valve body field of WCB or 304, and lining field of PFA and FEP.

Split valve body and clamp installation

This type of lined butterfly valve can adopt a valve body structure that is convenient for lining manufacturing and assembly, and is clamped by the flanges on both sides of the pipeline during clamping installation. The specific structural form and fastening requirements should be confirmed according to the actual product drawings.

PFA and FEP material selection

The actual lining should be determined based on the chemical properties of the medium, temperature, pressure, and usage conditions. The current parameters on this page do not have default options for PO and PTFE, so these materials will no longer be included in the current standard configuration.

Worm gear operation

The worm gear mechanism is used to reduce the operating force required for manual opening and closing, and to help control the opening of the butterfly plate; The actual operating torque should be determined according to the valve specifications and operating conditions.
