Features

• The valve body is forged Y type, has small flow resistance, and has a large CV value.

• The valve core has a throttle plate to effectively protect the sealing surface and prolong the service life of the valve.

• Valve core and seat surfacing overlaid hard alloy, after special technology and machining processing, anti-cavitation, erosion resistance.

• There are two guide rings on the core, the valve stem is balanced, the movement is flexible, and not easy for jamming phenomenon happen .

• The valve stem packings are all imported from the United States GARLOCK, with good chemical and flexibility, low friction, zero leakage and long service life (4-5 years).

• The switch speed is fast, generally 3-5 seconds, which effectively protects the system and greatly reduces the sealing time of the sealing surface.

• The bonnet is equipped with a heat sink to fully dissipate heat, ensuring that pneumatic actuators and solenoid valves are not subject to high temperature shocks. The mid-cavity gasket is a high-strength flexible graphite pad with better sealing and reliability than the general flexible graphite pad.
