What Makes JIS Gate Valve Essential?
JIS gate valves are known for their high reliability, durability, and long service life. They are widely used in various industries, including oil and gas, petrochemical, marine, and water treatment. A JIS gate valve consists of a gate, which moves up and down within the valve body to open or close the valve. The gate is guided by two seats, which provide a tight seal when the valve is in the closed position.
To understand why JIS gate valves are essential, let's take a look at the step-by-step process of how they work:
Step 1: When the valve is in the closed position, the gate is pressed tightly against the seats, preventing any fluid from flowing through the valve. This ensures no leakage and prevents any damage to the surrounding environment.
Step 2: To open the valve, the operator turns the valve handle, which rotates the stem and lifts the gate. As the gate rises, a gap is created between the gate and the seats, allowing the fluid to flow through the valve.
Step 3: When the valve handle is turned to close the valve, the gate moves back down towards the seats. As it comes into contact with the seats, the gate is held in place by gravity and the pressure of the fluid. This provides a secure seal, preventing any fluid from leaking through the valve.
Step 4: The design of JIS gate valves ensures that they are highly resistant to wear and tear, as the gate and seats are in contact for a relatively short period when the valve is being opened or closed. This reduces the risk of damage to the valve, increasing its overall service life.
Step 5: JIS gate valves are also designed to handle high pressures and temperatures, making them suitable for a wide range of applications. They can withstand pressure up to 20kg/cm² and temperatures up to 120°C.
In conclusion, JIS gate valves are an essential component in many industries due to their reliability, durability, and long service life. Their design ensures a tight seal, preventing any leakage and damage to the surrounding environment. They are also able to withstand high pressures and temperatures, making them suitable for a wide range of applications. When it comes to selecting a valve for your industry, JIS gate valves are a reliable choice for ensuring the safe and efficient operation of your systems.
