J-VALVES
Structural Features
Cast Steel Material: The valve body is made of GS-C25 cast steel, which offers high strength and good corrosion resistance, suitable for various media and working conditions.
Bellow Sealing: Adopts a bellow sealing design to ensure 100% leak-free performance at the valve stem, maintaining sealing performance even under high-temperature conditions.
Dual Sealing Design: The bellow provides metal sealing to prevent leakage; in case of bellow failure, the packing can serve as a secondary seal.
Flanged Connection: Both ends adopt a flanged connection method that complies with DIN standards, ensuring convenient installation and reliable sealing.
Compact Design: With small size and light weight, it is easy to install and maintain, particularly suitable for occasions with limited space.
Multiple Operation Modes: Handwheel operation is provided, which is easy to operate and suitable for manual control. Gear, pneumatic, or electric actuators can also be optionally equipped to achieve automatic control.
Fire Safety Design: Complies with relevant fire safety standards; even in case of fire, the valve can maintain sealing performance to safeguard the safety of personnel and equipment.
Anti-Static Device: A built-in anti-static device ensures electrical continuity, prevents static accumulation, and reduces the risk of fire and explosion.
