1.Introduction of Hard Seal Gate Valve

The opening and closing part of the hard seal gate valve is the gate, the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.


2.Structure of Hard Seal Gate Valve

The soft seal and the hard seal are for the sealing material of the valve seat. The hard seal is a metal-to-metal seal. The sealing surface of the valve body is metal, and the valve plate is also metal. The sealing materials of hard seal gate valve is generally stainless steel and copper.


The hard seal gate valve is composed of a valve body, a valve plate, a valve stem, and a valve cover seal. The gate plate and the sealing surface of the internal flow channel of the hard-seal gate valve are all welded by Stellite stacking.


The sealing principle of the hard seal gate valve is to drive the valve plate down by operating the valve stem of the handwheel. The reunion utilizes the hard-to-hard combination sealing effect of the wedge-type sealing surface inside the gate and the gate valve to complete the closing and blocking of the medium by the gate valve.


3.Application of Hard Seal Gate Valve

When the medium contains solid particles or has abrasion or the temperature is higher than 200 degrees Celsius, it is best to choose a hard-sealed gate valve. If the valve diameter is greater than 50mm and the valve has a large pressure difference and a large torque, a fixed hard-sealed gate valve should be used.
