product overview

This product can be driven by electric, pneumatic, manual, or bevel gear rotation devices. Pneumatic devices can be equipped with air filters, solenoid valves, and sensors. If the above driving devices are installed, the pneumatic device should be specified in the contract.

Note: The rubber grade depends on the properties of the medium and the operating temperature.
The material grade of the gate depends on the properties of the medium.

Shell Test and Seal Test
1. The shell test and sealing test media for plug-in valves are water (including preservatives), kerosene, or other suitable liquids with a viscosity not greater than water.
2. The sealing pair is a non-metallic sealed plug valve, and the sealing shell test and requirements are in accordance with GB/T13927-92D level regulations.
3. The sealing pair is a metal sealed plug valve. For those with sealing performance requirements, the leakage rate of the sealing test is 1 × DNmm³/S calculation, do not conduct this test for those without sealing performance requirements.
4. The plug-in valve driven by electric, hydraulic, and pneumatic devices should be closed three times after the position is set, and the shell and sealing tests should be conducted according to the requirements of 1 and 3.
5. The cleanliness requirements for plug-in valves shall comply with the provisions of JB/T7748.
6. Static pressure life test.
7. The number of static pressure life tests for plug-in valves shall be in accordance with the regulations, and other technical requirements shall be in accordance with the provisions of JB/Z234.

Note: 1. Metal sealing refers to the sealing auxiliary material being metal metal.
2. Non metallic sealing refers to the sealing secondary material being metal non-metal or non-metal non-metal.
