with scavenging hole gate Industrial Valves features:

1, with scavenging hole wedge gate valve gate valve series subject single ram two-way sealing, simple structure, compact, reliable sealing. 2, purging device for easy coking, granular medium pipeline, valve, etc for washing, flushing, effectively improve the service life of the system. 3, Z1 imitation, Z2 imitation series belt purging gate valves can also be applied to water, steam, gas, oil, or fog, powder, granule, such as medium of piping, as a lifting device to use, especially suitable for petrochemical industry oil and catalytic cracking system, opening and closing, wash wash pipe role.

gate valve installation and maintenance should be paid attention to the following: 1. The handwheel, handle and transmission mechanism are not allowed for lifting, and collision is forbidden. 2. Double disc gate valves should be installed vertically ( The stem in a vertical position, the handwheel at the top) 。 3. Gate valve with a bypass valve in open open the bypass valve should be taken before, To balance the import and export of pressure difference and reduce the opening force) 。 4. Belt transmission mechanism of the gate, according to the regulations of the product instruction manual installation. 5. If the valve switch is used, often lubrication at least once a month.
