the bellows gate valve open or close the valve stem travel relatively short, and very reliable cutting function, and due to the change of his seat and disc stroke proportional relationship, is very suitable for the traffic regulation.

as a result, this type of Industrial Valves is well suited for use as cut off or adjust and throttling.

1, all kinds of manual valves installed on the thermal insulation pipe, handle shall not down. 2 installation position, height, import and export direction must comply with the design requirements, the connection should be firmly connected. 3, corrugated pipe gate Industrial Valves a visual inspection must be conducted before installation, the valve nameplate should be consistent with existing national standards 'universal signal valve GB12220 rules. For the working pressure is greater than 1. 0 mpa and a cut on ZhuGanGuan

faulting valve, strength and strict performance test should be done before the installation, qualified rear must use. Strength test, the test pressure for the nominal pressure of 1. 5 times, duration of not less than 5 min, valve shell, packing should be

no leakage for qualified. Leak test, the test pressure for the nominal pressure of 1. 1 times; The duration of the test pressure in the test should conform to the requirements of the standard GB50243, with no leakage for qualified for Industrial Valves sealing surface.

the shortcoming of corrugated pipe gate valve as below

1, the fluid resistance is big, needed for opening and closing force is larger. 2, does not apply to take larger particles, viscosity, easy to coking of the medium. 3, poor regulation performance.

At a time when technology is essential for resilient wedge gate valve, ensuring that it works in a symbiotic way with your human employees is key.
