Product Description
The product can be provided with the following types of actuators: Electric, pneumatic, manual, taper gear, etc. The pneumatic actuator can be provided with an air filter, electromagnetic and sensor. To install the following actuators, the pneumatic actuator should be boted in the contract.
Note: The rubber grade is subject to the medium property and the working temperature; The material grade of gate is subject to the medium property.
Shell test and leakage test
1. The medium for shell test and leakage test of the screw gate valve includes water(containing presservatives), kerosene or other kinds of suitable liquid with a viscosity not larger than water.
2. For the screw gate valve with the seal pair adopting non-metal seal, the leakage and shell tests and requirements conform to provision of GB/T13927-92D.
3. Regarding the screw gate valve with the seal pair adopting metal seal, the leakage quantity for the leakage test is calculated by 1× DNmm3/s for those with requirements for sealability and no such provision for those without requirements for sealability.
4. For those screw gate valves provided with electric, hydraulic or pneumatic actuators, shut three times after the off position is set and then carry out the shell and leakage tests in accordance with requirements in 1 and 3.
5. The requirements for cleanness of the screw gate valve conform to provisions of JB/T7748.
6. Static pressure lift test.
7. The times for static pressure test of the screw gate valve are subject to the provisions and other technical requirements to provisions of JB/TZ234.
Note: The rubber grade is subject to the medium property and the working temperature; The material grade of gate is subject to the medium property.

Company Introduction:
Our factory manufactures the ball valve, gate valve, globe valve and check valve and so on. The pressure from 150 lb to 2500 lb, and ball valve from 1/2" to 56", gate valve from 1/2" to 36", globe valve from 1/2" to 16", and check valve from 1/2" to 36".
And our company manufactures the full welding ball valve size up to 56". It is only 1 companies can do in China.
Our company produce the metal to metal high pressure high temperature ball valve, top entry ball valve, large size full welding ball valve and 2500LB and 3000LB super high pressure ball valves are very famous in China and oversea.
We are as a professional valve manufacturer is engaged in producing of stainless steel, alloy steel and carbon steel valves. It was established in 1994 in Oubei, Yongjia county, Zhejiang China. The Oubei town has the wonderful name of "the matherland of the valve and pump in China". Oubei town is a good traffic and geographical position.
We had been certified by DNV ISO9001, API 6D and CE. And we have famous trademark in China that is Quality and Reputation AAA level enterprise. We produce all kinds of the ball valve, globle valve, gate valve and check valve etc. Our products have been exported to America, Canada, Australia, Europe, Middle East, southeast Asia, Japan, South Korea etc. The reliable quality and reasonable price are the foundation of our constant development.
We are studying in professional research and developing new goods. We are go on improving and developing new products. Some of them have obtained Chinese patents. Ceaseless creation is the spirit of Kelite. We would like to provide users with much more products of high quality and favourable price. And we welcome customers to visit us.
