详细介绍

Wafer type butterfly simple structure, small volume, light weight, only by a few parts. But only can be rotated 90 ° rapid opening and closing, simple to operate, while the fluid control valve has good characteristics. Butterfly valve is fully open position, the disc thickness is only when the medium flows through the body resistance, thus generated by the valve pressure drop is small, it has a better flow control characteristics. Butterfly valve with elastic metal seal and the seal two kinds of sealed type. Elastic sealing valves, seals can be mounted on the body or attached to the disc periphery.Common butterfly valve wafer type butterfly valve and flange type butterfly valve two. Wafer type butterfly valve is the valve connection between two pipe flanges stud bolt, flange type butterfly valve is a valve with a flange, on both ends of the valve in the pipe flange connection flange bolt.

Comparison of manual performance wafer type butterfly valve and gate valve

Nominal pressure and nominal diameter of the same common butterfly valve and gate valve rigor which is better, not easy water leakage?

Closed valve better than the butterfly valve, but also has the good sealing performance of the valve manufacturer.

Gate valve of large volume, large space occupation.

Butterfly valve has the advantages of small volume, small occupying space.

When the specific use, but also consider the temperature, the valve sealing and packing medium.

Specification nominal diameter greater than 50 with a butterfly valve.

Manual wafer type butterfly valve is a state-level key new products, high performance butterfly valves manually with a double eccentric, and a special oblique elliptical cone sealing structure. To solve the traditional eccentric butterfly valve in the opening and closing of 0 ° ~ 10 ° instant sealing surface is still in the ills of sliding friction, the butterfly plate sealing surface of the separation in the opening moments, close contact sealing effect, achieve the purpose of prolonging the service life, the best sealing performance.
