The sealing surface of Angle Globe Valve is made of babbitt alloy, tetrafluoroides, nylon, etc. Long service life. It is installed in the equipment or pipeline of the refrigeration system to connect and cut off the flow channel of the refrigerant, and can naturally achieve chemical treatment performance under the environment of temperature difference fluctuation during use. It is suitable for opening and closing of ammonia, ammonia liquid medium pipelines and liquefied gas pipelines with temperature of -40~+150 degrees Celsius. It is mainly used in freezing, refrigeration, chemical industry, petroleum, food, smelting, liquefied gas and other units.
Product characteristics
1. The middle flange is sealed with a mortise and groove surface structure, and the valve stem is connected with an interbar.
2. The sealing surface of the valve body is shaped like a ball and sealed with the valve foot.
3. Sealing surface adopts babbitt alloy, good sealing performance and long service life.
Standards and specifications
Nominal pressure: 2.5~4.0
Test pressure: 3.8~6.0
Working principle
The opening and closing part of the J44B Angle ammonia globe valve is a plug shaped valve disc, the sealing surface is flat or conical, and the valve disc moves in a straight line along the center line of the fluid. The movement of the valve stem has a lifting rod type (the valve stem is lifted, the handwheel is not lifted), and a lifting rotary rod type (the handwheel is rotated with the valve stem, and the nut is located on the valve body). The globe valve is only suitable for full opening and full closing, and is not allowed to be adjusted and throttled.
