Product Description

Introduction:

Hydraulic wafer Butterfly Valves
Feature
1.The valve has bidirectional sealing performance, which is suitable for both nomal flow and contraflow working condition.
2.The double offset stucture enables the valve excellent sealing performance.
3.The main material of body and plate is ductile iron and cast steel. Sealing material is stainless steel, acid-resiatant steel and PTFE (polyterafluroethylene) matching rubber ,which can be used for long time
4.Shaft have types of whole shaft, dice have truss structure and fluid structure, high intensity, large open area and small flow resitance.
5.Worm gesr actuator is a type of whole sealing, can be soaked in water and running free.
6.Flexible type bi-directional sealing butterfly valve can free expansion as wellas fixed limit or according to the work condition.
Working Principle
Worm gear operator bi-directiomal rubber soft sealing butterfly valve include flange type,flexible type via turning hand wheel or taper shank square head etc. to reduce ration, worm gear drive valve shaft,disc revolve within 90° to truncate,Connect or regulate flow. Electric operator bi-directional rubber soft sealing butterfly valve via electrical actuator drive shaft, disc revolve within 90° to close and open.
Valve closure and opens are limited by limit button both worm gear actuator and electric actuator, and there is a indicator control status switch of the disc.
