Pneumatic Trunnion Mounted Ball Valve are based on the needs of users. In order to meet the requirements of sulfurization application cracking in vulcanized environments, this series of high -pressure forging steel balls from design, selection, manufacturing, testing, surface foreign foreigners and paint are strictly corrosive according to the United States. Engineers' NACE standard requirements are required.
Pneumatic Trunnion Mounted Ball Valve Metal Seat
This series of ball valves not only have a wide range of materials, but also the internal materials are made of nickel -plated 316 materials on the surface, and the sealing ring is made of special polymer materials. Make valve not only anti -corrosion, strong anti -sulfurization capacity, good fire prevention, anti -static, sealing performance, wide use pressure and temperature range, complete diameter and contraction diameter, and can be equipped with a variety of drivers. It is a chemical and oil torch refining manufacturing , Natural gas mining and conveying system ideal valve selection. The main function:
When the medium of stagnation in the middle of the valve is abnormal due to temperature changes, the medium pressure pushes the valve seat to leave the sphere to achieve the effect of automatic pressure discreation, and Pneumatic Trunnion Mounted Ball Valve seat is automatically reset after pressure.
In addition to the general sealing of the valve seat, the specially set sealed structure can play an emergency rescue effect when leakage occurs due to the damage of the seal.
When the fire or different temperature causes the valve seat to be sealed or softened. The operation of Pneumatic Trunnion Mounted Ball Valve is reliable. At the same time, the valve seat and the sphere form a metal to the metal to achieve temporary sealing effects, preventing the fire from further expanding and complied with the regulations of AP16FA.
The exclusion device can check whether the valve seat is leaked, or it can also discharge the retention of the medium in the middle of the cavity to reduce the unilateral pollution of the medium on the valve. When the valve is full or full level, the valve sink filling letter can be replaced.
The sealing of the valve stem is dual seal with PTFE filler and O -shaped ring, which is especially suitable for gas media. The motion of the valve stem uses a high -quality SF self -lubricating bearings to make the friction coefficient smaller and reduce the operating torque.
