Product Introduction

This series of butterfly valve is a new generation of patented products which is independent researched and developed by our company, no pin connection is through a valve rod milling flat straight connected with the butterfly plate matched,with countersunk head bolt is fixed, is more convenient in assembly, firmer connection security.Use triple eccentric sealing structure,no mechanical wear, can achieve zero leakage, with bidirectional sealing function superior, is used as the best device in oil,chemical industry,metallurgy, electric power, building materials,food, medicine,water supply and drainage, gas delivery ofdifferent media, such as adjust,cut off or connected to the fluid flow.

WESDOM valves are installed all over the Asia,Africa continent, the Middle East and throughout Europe. They have justifiably acquired a faultless reputation for their durability, reliability and quality worldwide.

Motorisable butterfly valve features:


1.Protection of gearbox IP 68-8 (submersion up to 8 m of water) and actuator IP 68 (submersion up to 8 m of water, during 96 hours and 10operations)

①With position indicator.

②Clockwise Close (CC).

③For installation above ground and in non-flooded chambers.

④Designed and tested to an endurance level of 2500 cycles minimum, inaccordance with EN 1074-1 and 2.

⑤Supplied with a handwheel.


2.Reduces resilient seal’s wear and tear ensuring detachment from the body seat ring the moment the valve begins to open.

①reduces pressure loss in fully open position by the disc

②parking in a zone of reduced flow.

③lower torque requirement to rotate the disc leads to less

④wear and longer life of the gasket and other elements.
