Product Details

The gas-specific flat gate valve is a gate valve structure that controls gas delivery. The purpose is to provide a gas gate valve that can improve the sealing performance and achieve zero leakage. This product has simple structure, reliable sealing, small switching torque, long service life and cleaning The advantages of stolen goods in the cavity are especially suitable for urban natural gas pipelines with working pressure ≤10Mpa and working temperature ≤120℃.

1. Product overview of gas flat gate valve

The flat gate valve is a sliding valve whose closing member is a parallel gate. The closing member can be a single gate or a double gate with a spreading mechanism in between.

The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a double gate flat gate valve, the expansion mechanism between the two gates can supplement this pressing force

2. Product advantages of gas-specific flat gate valve

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.

3. Models and principles for selection of gas-specific flat gate valve products

1. For oil and natural gas pipelines, flat gate valves with single or double gates are used. If you need to clean the pipeline, use single or double gate open-rod flat gate valve with diversion holes. (Z43F/Z44H)

2. For the transportation pipeline and storage equipment of refined oil, use single gate or double gate flat gate valve without diversion hole. (Z43WBF/Z44H)

3. For oil and natural gas exploitation wellhead devices, single-gate or double-gate flat gate valves with dark rod floating valve seats and diversion holes are selected, most of which are API16A standards, and the pressure levels are API2000, API3000, API5000, API10000, API15000, API20000.

(2 1/16”- 7 1/16” 2000-20000 PSI PR1. PR2 PSL1-PSL4 AA. BB. CC. DD. EE. FF)

4. For pipelines with suspended particulate media, use hard-sealed flat gate valves or knife-type flat gate valves. (Z43WH/PZ73H)

5. City gas transmission pipeline, select the buried gas dedicated flat gate valve. (MZ47F)

6. For urban tap water projects, single-gate soft-sealed open-rod flat gate valve is selected. (Z43WBF)

Four, product use

1. (Class150~900/PN1.0~16.0MPa, working temperature -29~121℃) oil and natural gas transmission pipeline. 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.
