The API 600 gate valve is widely used in our country's valve market for its large flow, good sealing performance, high reliability, and simple maintenance. API 600 gate valve: compact structure, light weight, small installation size, small friction resistance between seals.
1. API 600 gate valves are distinguished by a body made of metal carbide, valve pieces, and seat seals that are one of the casting molds with good sealing.
2 The API 600 gate valve has two through holes, one for medium flow upwards and one for medium flow downwards.When the valve is closed, the hydraulic pressure in the valve acts on the valve sheet, which can effectively prevent the fluid pressure generated when the valve is closed. Under the action of pressure, the pressure drop is lower and the opening and closing moments are shorter.
The 3  API 600 gate valve is a double-sealed, soft seal to ensure that when fully open or fully closed, there will be no liquid mixed between the valve and the gate.
4 When the American Standard valve is closed, the flow direction of the medium is the same as the arrow shown on the valve, that is, the medium flows from top to bottom.
5 The American Standard Valve's opening and closing torques are unaffected by medium pressure, and its opening torque is far less than that of a API 600 gate valve.
2. Characteristics of electric and pneumatic API 600 gate valves: There are many kinds of electric and pneumatic API 600 gate valves, but their performances are not very different, so they can be chosen according to the needs of customers.
