Funcation description

Application:The gate valves are suitable for use in potable water, sewage, fire protection, oil, gas, and environmental protection equipment system

THT gate valve is a type of valve with gate to open and close The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve is commonly used in water oil and gas pipework. It is reliably in sealing and economic in price.

For water works with normal temperature, resilient seat gate valve is a good choice for its most reliable sealing by rubber compensation.

For oil and gas pipe where need higher pressure or temperature, we need metal sealing with more thrength material.

For very low pressure air, we could produce you light type to save cost at the same time meet your need.

For working site where there is limit space to install, we could supply you knife type gate valve if working condition allowed.
