GB Standard Globe Valve Cast Steel Forged Steel Petrochemical Power Plant China Manufacturer Supplier

Economy and longevity

Economy and longevity
01
Optimize the structure to reduce wear points, and use valve stems that have undergone quenching, tempering, and nitriding treatment to significantly extend their service life;
02
Standardized manufacturing complies with national standards (such as GB12235), ensuring interchangeability and reducing operation and maintenance costs.

Multi functional adaptability

Multi functional adaptability
01
Provide straight through, straight through, and angled channel designs to meet different fluid resistance requirements (with straight through having the lowest flow resistance);
02
Some models use double sealing with corrugated pipes and packing to prevent the leakage of toxic and flammable media, which meets industrial safety standards.

Convenient operation and low maintenance cost

Convenient operation and low maintenance cost
01
Simple structure, supporting handwheel, electric or pneumatic actuators, convenient for remote and on-site operation;
02
The detachable valve seat design facilitates the cleaning of coking or particulate matter, and there is no need to disassemble the seal as a whole when replacing it.

Excellent sealing performance and low wear

Excellent sealing performance and low wear
01
Cobalt based hard alloy overlay sealing surface (such as Stellite) is wear-resistant and corrosion-resistant, combined with forced sealing design to achieve zero leakage;
02
The valve disc is in contact with the single sealing surface of the valve seat, with low friction, and can maintain sealing reliability even after long-term use.

High strength structure and pressure resistance performance

High strength structure and pressure resistance performance
01
The valve body is made of forged steel/stainless steel material, with a compact design that can withstand high pressure (≤ 32MPa) and high temperature (≤ 570 ℃) working conditions, suitable for high demand fields such as petroleum and chemical industry;
02
Short stroke design (fully open height of 25% -30% of nominal diameter) reduces valve disc movement distance and improves opening and closing efficiency.
