Z43WPF light flat gate valve

product description:

The light-duty flat gate valve is suitable for oil storage and transportation projects in port terminals or airport oil depots with Class150～900/PN1.0～16.0MPa and working temperature of -29～150℃. It plays the role of pipe media interception and adjustment;

Application range:

1. Oil and natural gas pipelines. The flat gate valve with diversion hole is also easy to clean the pipeline.

2. Transportation pipelines and storage equipment for refined oil.

3. Oil and natural gas extraction wellhead devices, that is, valves for Christmas trees.

4. Pipes with suspended particles.

5. City gas transmission pipeline.

6. Tap water works.

Structural features:

1. The valve seat adopts an O-ring seal and a floating seat structure that applies pre-tightening force to seal the inlet and outlet of the flat gate valve in both directions; and the opening and closing torque of this structure is only 1/2 of that of ordinary valves, which can achieve easy opening and closing. Close the valve

2. When fully opened, the channel is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss, and the pipeline can be cleaned by the hair ball

3. The packing structure with self-sealing capability is adopted, without frequent adjustment, the opening and closing are extremely light, and the sealing performance is reliable. There is an auxiliary sealing grease injection structure at the stuffing box, the sealing performance is absolutely reliable, and the zero leakage is truly achieved; it solves the general purpose Disadvantages of easy leakage at valve packing

4. When the flat gate valve is closed, the high pressure in the cavity can be automatically removed to ensure safe use

5. Fully enclosed structure, good protection performance, can adapt to all-weather requirements

product advantages:

The flow resistance is small, and its flow resistance without shrinking is similar to that of a short tube. The flat gate valve with diversion hole can be directly used for pigging when installed on the pipeline. Since the gate slides on the two valve seat surfaces, the flat gate valve fluid can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually automatically positioned. The seat sealing surface will not be damaged by thermal deformation of the valve body. Moreover, even if the valve is closed in a cold state, the thermal elongation of the valve stem will not overload the sealing surface. At the same time, when the valve is closed, the flat gate valve without diversion hole does not require the closing position of the gate to have a higher accuracy, so the electric flat valve can control the opening and closing position by the stroke.
