Product introduction

Product description

Z41H/Y/W-16~100C,P,R

Main features and uses:

Compact structure, reasonable design, good valve rigidity, smooth channel and small flow resistance coefficient.

The sealing surface is made of stainless steel and cemented carbide, with long service life.

Flexible graphite packing, reliable sealing, light and flexible operation.

The driving mode is divided into pneumatic, electric, pneumatic and gear transmission.

Structural form: elastic wedge single ram, rigid wedge single ram and double ram.

It is widely used in petroleum, chemical industry, thermal power plant and other oil and steam pipelines as opening and closing devices to connect or cut off the medium in the pipeline.
