Direction of Valve Installation

Many valves are directional in installation, such as globe valve, throttle valve, pressure reducing valve, check valve, etc. if the position is reversed, the service effect and service life of the valve will be affected (such as throttle valve), or it will not work at all (such as pressure reducing valve), or even cause danger (such as check valve). General valve, there is direction mark on the valve body. If not, it should be correctly identified according to the working principle of the valve.

Valve installation position must be convenient for operation

1.Even if the installation is difficult , but for the long-term work of operators should be considered. It's better to make the valve handwheel flush with the chest (generally 1.2m away from the operation floor), so that the opening and closing of the valve is less effort. The hand wheel of the floor valve should be upward, not inclined, so as to avoid the operation. The valve of wall machine and equipment should also leave room for operators to stand.

2.To avoid the sky operation, especially acid-base, toxic media, etc., otherwise it is not safe.

3.Do not install the gate upside down (i.e. the hand wheel is downward), otherwise the medium will remain in the valve cover space for a long time, which is easy to corrode the valve stem, and is taboo for some process requirements. It is very inconvenient to change the packing at the same time. Do not install the rising stem gate valve underground, otherwise the exposed stem will be corroded due to moisture.

4.Lift check valve, installation to ensure that its disc vertical, in order to lift flexible. Swing check valve, installation to ensure its pin level, in order to swing flexible. The pressure reducing valve shall be installed vertically on the horizontal pipeline, and shall not be inclined in all directions.
