Product Description
High pressure forged steel ball valves are designed, selected, manufactured, tested, surface treated, and painted in strict accordance with the requirements of the American Society of Corrosion Engineers (NACE) standard to meet the cracking requirements of sulfurization applications in sulfurization environments according to user needs.
This series of ball valves not only has a wide selection of materials, but also the internal materials are all made of surface nickel plated 316 material, and the sealing ring is made of specially made polymer material. The valve is not only corrosion-resistant, but also has strong sulfurization resistance, fire resistance, anti-static, and good sealing performance. It has a wide range of pressure and temperature, and can be equipped with various driving devices. It is an ideal valve choice for chemical, petroleum torch refining, natural gas extraction and transportation systems.
When the stagnant medium in the valve chamber experiences abnormal pressure rise due to temperature changes, the medium pressure pushes the valve seat away from the ball, achieving automatic pressure relief. After pressure relief, the valve seat automatically resets.
In addition to general sealing, the valve seat has a specially designed sealing structure that can provide emergency rescue in case of leakage due to damage to the sealing ring.
When a fire or abnormal temperature causes the valve seat sealing ring to burn or soften. The valve operation is still reliable, and at the same time, the valve seat and ball form a metal to metal relationship, achieving temporary sealing effect and preventing further expansion of the fire, in accordance with AP16FA regulations.
Turning on the discharge device can check whether the valve seat is leaking, and can also discharge the residual substances in the middle chamber to reduce the pollution of the medium on the valve side. When the valve is fully open or fully closed in working condition, the valve stem packing box can be replaced.
The valve stem is sealed with PTFE packing and O-ring, making it particularly suitable for gas media. The moving part of the valve stem adopts high-quality SF self-lubricating bearings, which reduces the friction coefficient and reduces operating torque.
