Can knife gate valves be arranged horizontally? How to operate it specifically?

1、 Can knife gate valves be arranged horizontally?

Knife gate valves can be installed horizontally, but several key points need to be noted:

1. Medium characteristics: If the liquid flowing in the pipeline contains solid particles, it is recommended to turn the valve handwheel or actuator towards the upstream direction of the medium flow, which can reduce the problem of particle accumulation at the bottom of the valve.

2. Weight of actuator: If the valve is equipped with a heavy handwheel or electric device, it is recommended to add a support frame to avoid deformation of the valve due to long-term use.

3. Sealing design: Choosing a double-sided sealed knife gate valve is more suitable for horizontal installation, but it is necessary to regularly check the wear of the sealing components.

2、 How to operate knife gate valve safely?

1. Switching force: Do not use excessive force during operation, stop when there is obvious resistance. Electric valves must ensure that travel limits are set.

2. High pressure differential operation: In a high-pressure system, the pressure should be balanced through a bypass valve before operating the main valve.

3. Confirmation of switch status: The valve should either be fully open or fully closed, and should not stay in the middle position, as this can easily damage the sealing surface.

3、 What should be paid attention to in daily maintenance?

1. Regular lubrication: The valve stem and moving parts need to be lubricated, and appropriate lubricants should be added regularly according to the frequency of use.

2. Leakage inspection: Regularly check the valve for signs of leakage, especially in the sealing area.

3. Preventive maintenance: Develop a regular inspection plan, including checking whether the valve plate moves smoothly and whether the sealing surface is intact.

Kind Reminder

Valves from different manufacturers may have different requirements, so be sure to read the instruction manual before use. It is recommended to conduct a comprehensive inspection of valves in important areas once a year to ensure safety and reliability. If any abnormal operation or leakage is found, it should be stopped and repaired in a timely manner.
