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


Body Material 

1. High temperature material
2. Low temperature material
3. Cryogenic material

In-valve component material
Commonly used valve assembly materials are SUS304, SUS316, SUS316L, USU410, SUS420, etc.

Flow characteristics

1. Linear flow characteristics
2. Equal percentage flow characteristics
3. Quick open

Stuffing box structure

Labyrinth control valve 
Based on the mechanism of fluid mechanics, the labyrinth control valve adopts and applies the technology of speed control principle, and uses multistage pressure reduction to eliminatecavitation, flashing, vibration and noise, providing a comprehensive system for many different application fields. Control solution.
The labyrinth control valve can effectively eliminate the damage caused by the out of control of the fluid velocity.


Pneumatic actuators

The L1000 series pneumatic actuator is a multi-spring diaphragm actuator with light weight, small size and stable output.
L2000 linear multi-spring pison pneumatic actuator with the same principal as multi-spring diaphragm  actuator . However, the series of actuators replaced the diaphragm with a pison. This change solved the problem of the diaphragm actuator could not withstand the pressure of the large air source and the diaphragm was aging. Enables the actuator to withstand greater air supply pressure.
The increase in air supply pressure directly increases the output of the actuator. 



Stem seal design
The v-type flexible graphite is adopted as the filter structure and the high-temperature type stuffing box structure. The design of v-type flexible graphite has changed the disadvantages of the former flexible graphite packing without compensation and deformation, and the sulfur-free flexible graphite material can ensure the longest service lift of the filler.
The high-temperature type stuffing box structure with sulfur-free v-type flexible graphite is adopted to increase the preload compension design of spring gasket to ensure the long-term use of stuffing box without maintenance.
Standard stuffing box module to withstand pressure and temperature range:
Maximum pressure: Class 600 /64 MPA
Temperature range: 196 degeree+250 degree
Pressure and temperature range of high temperature type stuffing box module :

Temperature range: 196 ºC to 250 ºC
