Stainless steel pneumatic O-type cut-off insulation ball valve asphalt valve

Stainless steel pneumatic O-type cut-off insulation ball valve asphalt valveProduct Introduction

The QJ (D/S) RB precision small pneumatic insulated O-type cut-off ball valve is composed of a lifting self-control valve pneumatic piston actuator and a sandwich integral cast valve body. The valve core is a cylindrical through-hole sphere. The pneumatic ball valve seat is designed to have a spring like rebound effect to form a double flexible valve seat, ensuring the reliability of the ball seal. At the same time, the medium pressure and the rebound force of the upstream flexible structure increase the sealing of the downstream valve seat. The flexible structure automatically compensates for the wear, temperature, and pressure changes of the valve seat, thereby improving its service life. This product has the advantages of easy disassembly and maintenance, clean appearance, compact size, and good insulation effect. It can be widely used in fluids that are prone to crystallization and viscosity, and can meet various occasions that require insulation media. Controlled media such as petroleum with high wax and asphalt content are used to prevent crystallization of the media and ensure efficient operation of the self-control system.
