Product Introduction
Company Profile
Product Features & Operation Points
- High-pressure optimized design with a nominal pressure of P55.560 (55.5MPa), precisely matching the operational demands of key high-pressure pipelines in thermal power, hydropower, nuclear power and new energy projects, effectively realizing rapid air and non-condensable gas exhaust while preventing medium leakage, eliminating air blockage and water hammer hazards, and supporting YOYIK's efficient power solutions.
- Scientific flow channel and exhaust structure greatly reduces exhaust resistance, ensures smooth and rapid discharge of air and non-condensable gas, mitigates erosion and corrosion damage to the valve seat and clack caused by high-velocity media, and ensures long-term stable and reliable exhaust performance in industrial high-pressure pipelines, which is consistent with the structural advantages of high-pressure pneumatic air exhaust valves.
- Superior material performance: The valve body is made of ZG15Cr1Mo1V alloy steel, which has excellent high-temperature creep resistance, pressure-bearing capacity, corrosion resistance and wear resistance, perfectly adapting to the harsh high temperature and high pressure working conditions of high-pressure pipelines in thermal power, hydropower, nuclear power and new energy projects, and consistent with YOYIK's high-standard product requirements supported by its independent R&D capabilities.
- Adopts efficient pneumatic actuator operation and metal-to-metal seating precision structure; the valve clack and seat are precision ground to achieve tight sealing effect, while the pneumatic control ensures quick response, stable operation and easy remote control, realizing automatic and rapid exhaust, suitable for automatic control scenarios in high-pressure pipelines of various power projects. The valve stem is treated with special surface treatment to reduce friction, ensuring no external leakage during long-term operation and facilitating on-site operation, maintenance and debugging, matching YOYIK's reliable service support.
- Strictly complies with international industry standards such as API 623, ASME B16.34 and GBT 12224, and all products pass strict performance testing (supported by YOYIK's strong independent R&D capabilities), ensuring excellent interchangeability with existing industrial equipment at home and abroad and simplifying on-site maintenance and spare part replacement processes, supported by the company's complete global supply chain management system.
