Product Description
Technical description
Forged steel ball valve works by rotating the valve stem to make the valve flow or occlusion. Can full bore ball valve, 90 degree angle, valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries. Forged steel ball valve classification: low pressure forged steel ball valve, high pressure forged steel ball valve.
High pressure forged steel ball valve according to the needs of users, in order to meet the curing environment in sulfide cracking application requirements, this series of high pressure forged steel ball from design, material selection, manufacturing, testing, surface treatment and painting are in strict accordance with the NACE standard requirements of corrosion engineers.
This series of ball valve is not only a wide range of material and the inner parts of the material are painted with the surface of nickel plated 316 material, sealing ring using a special polymeric material. The valve not only anti corrosion, anti sulfur ability, fire prevention, anti-static, good sealing performance, the use of a wide range of pressure and temperature, full size and reduced diameter are available, and can be equipped with multiple driving devices, chemical industry, petroleum refining torch, natural gas transportation system with the ideal valve selection.
Main function:
Valve in the middle of the cavity due to temperature changes in the medium and the people often boost pressure, the media pressure to push the valve seat out of the sphere, to achieve the effect of automatic pressure relief, pressure relief valve seat automatic reset.
In addition to general sealing valve seat, in particular, the sealing structure, can play the role of emergency rescue due to sealing ring damage and leakage occurs.
When the fire or abnormal temperature of the valve seat sealing ring is damaged or softening. Valve operation is still reliable, at the same time, the valve seat and ball to form a metal to metal, to achieve a temporary sealing effect, prevent the fire to further expand, in compliance with the provisions of AP16FA.
Unscrew the elimination device can check whether the valve seat leakage, can also reduce emissions in the retentate chamber medium on the valve on unilateral pollution. In the working state, the valve is fully open or fully closed, can replace the stem packing department.
The valve stem position is sealed by PTFE packing and O - shaped ring, and is especially suitable for gas medium. The valve stem is made of high quality SF self lubricating bearing, which makes the friction coefficient smaller and reduces operating torque.
