Integrated American standard flange ball valve Cl150 ASME B16.5
The integrated ball valve adopts precision casting technology to form a seamless valve body structure, and the main components consist of a valve body, a sphere, a valve seat, a valve stem, and a sealing component. Compared to the split structure, it reduces potential leakage risk points and improves overall strength compared to ordinary structures. The valve body flow channel can achieve a smooth transition of medium flow through computer fluid dynamics optimization. The composite design of multi-level soft seal and metal seal is suitable for the working environment from - 29℃ to 150℃. The valve seat is made of PTFE reinforced material, and the friction coefficient is kept at a low level.
90° rotary opening and closing design with anti-static structure, equipped with ISO5211 standard installation platform, compatible with multiple drive devices. The valve stem and sphere are connected by square tenons, which improves the torque transmission efficiency compared to traditional structures.
Applicable field performance
In the pipeline systems of petroleum, chemical, water and other fields, it exhibits reliable truncation performance. It has stable performance under conventional pressure levels (PN16-PN40). During maintenance, the sealing grease can be replenished through the grease valve to extend its service life.
Quality Control Standards
The manufacturing process follows the GB/T12237 national standard, and each valve undergoes a shell test at 3.5 times the rated pressure and a sealing test at 1.1 times the pressure.
Common problems in product selection
Can the integrated Q41F directly replace the existing Class150 ball valve?
The flange standard, structural length, sealing surface, channel diameter, and allowable pressure at working temperature should be checked simultaneously. Class cannot replace connection and material verification.
Can the seat of the integrated ball valve be replaced and does it need to be disassembled?
The assembly method and maintenance diagram of the valve body for this specification should be reviewed to confirm the direction of valve internals removal, required space, and spare parts. The integrated name cannot be directly used to determine whether online maintenance is possible; Before any dismantling inspection, isolation and pressure relief should be carried out.
Q41F is used for corrosive liquids. Should the valve body and seals be selected together?
Need. The composition, concentration, temperature, and pressure of the medium should be provided, and the compatibility of the valve body, sphere, valve stem, and valve seat should be checked separately. It is not enough to assume that all liquid receiving components are suitable just by selecting a stainless steel valve body.
