Description

Carbon Steel Gate Valve

This product,compact structure, reasonable design, good valve rigidity, smooth passage and small flow coefficient.

The GOST Carbon Steel Gate Valve, sealing surface is made of stainless steel and hard alloy, with long service life.

Using flexible graphite packing, the sealing performance is reliable compared with other products, and the operation is light and flexible.

The GOST Carbon Steel Gate Valve are widely used in water pipelines, oil pipelines and steam pipelines.

Ensure product safety and ease of use.

The driving mode is manual, pneumatic, electric, gear transmission, and you can choose according to your different needs.

GOST Carbon Steel Gate Valve, The structure is elastic wedge single gate, rigid wedge single gate and double gate

Because the valve has a wide range of uses, the working conditions of the valve sealing surface vary greatly. The pressure can range from vacuum to ultra-high pressure, the temperature can range from -40°C to 425°C, and some working temperatures can reach 1200°C. The working medium ranges from non-corrosive media to strong acid and corrosive media such as acids and alkalis. Therefore, according to different conditions of use, select the appropriate sealing material.
