Coaxial valve YQZF

The coaxial valve has the characteristics of anti -pollution, high flow, small volume, fast response speed, exemption of maintenance, back pressure sealing, long life and other characteristics.


Coaxial valve, pneumatic booster pump

Product Description

| Product introduction

  • The coaxial valve adopts the integrated structure of valve body and actuator, and the actuator coincides with the axis of the fluid pipeline to maximize the installation space and minimize the influence of fluid pressure difference on the valve opening force. Used to control various media, gaseous, liquid, gel-like, particulate, highly contaminated and corrosive. Compared with ordinary valves, the design of coaxial valves has the characteristics of controlling high flow and high pressure. Coaxial valves are used in machine tool cooling and lubrication, oil exploitation and treatment, gas production equipment, powder metallurgy, high-pressure washers, pressure grouting machines, blowing machines, sewage discharge equipment, foaming equipment, high-pressure testing equipment, laminar flow cooling, vacuum equipment.

    • 50-in-<> function, more
    cost-effective• Single product combines two functions, -Switch control of pipelines -Control the action
    of this switch• Greatly save installation space -Ready to use, save the space
    of traditional cylinders, joints and valves• Save a lot of installation time, save <>%
    of the installation man-hours of traditional cylinder valve groups • Safe and reliable, Reduces multiple connection handover surfaces during installation of traditional cylinder brake valves, making maintenance easier
    • Balanced design, zero differential pressure start, low driving force
    • Straight-through design, low pressure drop
    • Complete product range compatible
    with a wide range of media• Complete valve functions: normally closed, normally open, double-acting
    • NUMAR standard pneumatic mounting interface, More solenoid mounting options
    • VITON and EPDM seals are available
