Product Details

Description:

With four types: forged steel globe valve, non return globe valve, NPT globe valve, educed port globe valve and single seated globe valve, the A105 forged steel NPT pneumatic straight type globe valve is composed of a piston-type pneumatic actuator, with a solenoid valve, an air filter pressure reducing valve, a signal feedback device and a stainless steel connection. It adopts the self-sealing working principle, the medium enters the valve cavity from above the valve flap. Under the action of the medium pressure, the closing force of the shut-off valve is small, and the opening force is large, and the diameter of the valve stem can correspondingly reduce the impact force of the fluid. It relies on the stem pressure to tightly bond the disc sealing surface to the seat sealing surface to prevent media flow. However, it is not suitable for throttling and conditioning conditions.

Features:

  • The structure is simple, and the manufacturing and maintenance are convenient.

  • The working schedule is small and the opening and closing time is short.

  • The sealing surface is not easy to wear and scratch, and the sealing property is good.

  • There is no relative sliding between the valve flap and the sealing surface of the valve body during opening and closing, the friction is small, and the service life is long.

  • The fluid resistance is large, and the force required to open and close is large.

  • Not suitable for media with particles, high viscosity, and easy to coke.图片34.png
