Product Description

Waits Valve high quality Electric Knife Gate Valve uses a motor to drive the valve plate to open and close. It is suitable for automated control scenarios. The valve has a self cleaning function. When the valve is opened, the particles will be pushed away from the gate. To further protect the packing gland, a scraper can be optionally provided. Its advantages include high adjustment accuracy (capable of accurately controlling the opening) and stable torque output. It is often used in large diameter pipelines that require remote operation, such as sewage treatment and power systems. Maintenance requires regular inspection of the motor insulation and the lubrication status of the gears, but attention should be paid to the stability of the power supply.

Detail:

Electric Knife Gate Valve has a replaceable top packing gland, and the seal can be replaced without disassembling the valve.

Bidirectional, can be installed independently of the flow direction.

Full bore, no flow reduction.

Flat bottom prevents sediment accumulation.

No cavity in the valve body, no risk of clogging.

U shaped one piece NBR seals between the valve body parts compensate for tolerances in the coating and casting process. The seal is reinforced with a steel liner to prevent damage during operation.

Caged stem with bracket, can be installed with micro switches and inductive sensors
