Chase diameter coaxial valve YQZF(H)

Features: there are anti -pollution, large flow, low operating pressure, fast response speed, maintenance -free, back pressure seal, automatic valve core


Coaxial valve, pneumatic booster pump



Product Description

| Product introduction

High pressure resistance: balanced structure design, different from traditional valves, coaxial valve switch only needs to overcome friction
to prevent blockage: very suitable for particles, viscous and easy to condense media control
longer life: even in complex and harsh applications, coaxial valve service life can reach tens of millions of times, more than ten times that of conventional valves. The unique structure of the coaxial valve ensures that the axial seal is not subjected to lateral forces and eccentric loads, and the seal life is longer and the response is fast: the pressure-balanced design, the medium pressure on the valve stem is extremely low, and the stem stroke is
short, providing fast and repeatable operation. The maximum opening and closing time can be up to ten milliseconds, which is suitable for applications requiring high-speed switching
