The Introduction of Product's Details
Body Form

1. Straight valve body

 Features
    The through valve body is S-streamlined with smooth inner wall and        equal cross-section. It has the characteristics of small pressure loss, large flow rate and smooth flow.

1. Angled valve body 

Features
It has the characteristics of compact structure, simple flow path and small resistance.  Suitable for coking, clogging, high viscosity and other working conditions.

1. Three-way valve body

Three-way valve body mainly suitable for high pressure conditions, with good compressive strength. The internal flow path is simple, and it is not easy to produce vortices, reflux and other phenomena. Reduce the possibility of flash and turbidity under high pressure difference.


Bonnet Form
1.Standard bonnet
Features
    The through valve body is S-streamlined with smooth inner wall and        equal cross-section. It has the characteristics of small pressure loss, large flow rate and smooth flow.
 Operating temperature: -30 degeree-260 degree
2.High temperature bonnet
The high temperature cover is specially designed for high temperature working conditions. It can increase the contact area between the cover and the surrounding air by radiating fins, thus playing the role of heat dissipation.
Effective  protection of fillers and actuators.
Working Temperature: +230 degree-530 degree
                   -45 degree- -5 degree

3.Low temperature extended bonnet
Suitable  for low temperature medium (such as liquid oxygen, liquid nitrogen). The cover can effectively protect the packing and actuator. The standard material is 304 or 316. The material with different expansion coefficients can also be used according to the working conditions.
Working Temperature:-196 degree-45 degree

4.Metal bellows seal bonnet
The metal bellows seal valve cover is equipped with stainless steel bellows assembly, which isolates the medium from the outside world and ensures the stem to move up and down. In addition, there is still a standard packing box inside the upper valve cover to ensure that no waste or environmental pollution is caused by leakage of media.
Working Temperature -60 degree-530 degree.
