Z43WF flat gate valve is suitable for cutting off or connecting the medium in the pipeline of petroleum, natural gas, water, oil, etc., Class150 ~ 900/PN1.0 ~ 16.0mpa, operating temperature -29 ~ 121℃
1. The valve seat adopts the o-ring seal and the floating valve seat structure with pretension to make the inlet and outlet of the flat gate valve bidirectional seal; Moreover, the opening and closing moment of the structure is only 1/2 of that of ordinary valve, which can easily open and close the valve. This kind of valve should be installed horizontally in the pipeline.
2. When fully open, the channel is smooth and linear, with minimal flow resistance coefficient and no pressure loss, and the pipeline can be cleaned through the bulb
3, the use of packing structure with self-sealing ability, no need to frequently adjust, open, close is very light, and the sealing is reliable, the stuffing box is equipped with auxiliary sealing grease injection structure, the sealing performance is absolutely reliable, to achieve zero leakage; It solves the defect of easy leakage in general valve packing
4. When the flat gate valve is closed, it can automatically remove the inner cavity high pressure to ensure safe operation
5, fully closed structure, good protective performance, can adapt to all-weather requirements
Instructions for ordering:
1. If there is no selected model, please provide detailed parameters, such as medium, temperature, pressure, caliber, material, etc., and our technicians will select the model for you
Ii. If the selected model is available, please provide it according to the selected model
Non-standard products shall be provided with samples or confirmed by drawings
Note: the information is for reference only, or may not be complete, so we apologize for any inconvenience caused to you. The company can be selected according to different requirements and parameters. The company has various sizes of caliber, pressure, different materials, connection mode, drive mode, to meet different needs of various types of gate valves. Please contact 021-6651 8677 or consult online.
