Bi-directional Butterfly Valve
- This product is researched and manufactured by ZECO Valve for many years, which overcomes the shortcoming of the traditional metal seal butterfly valve, which is pressured from a single direction.
- This product is designed with a good seat, which can be maintained and increase sealing under opposite direction pressure automatically. This design is unique, scientific, and reliable.
- This product has been tested many times and some clients said the pressure in opposite direction is the same as the positive direction. It can ensure the opposite direction sealing according to normal pressure 1.1 times.
- It adopts a multiplex sealing structure between seat and body. The sealing performance is very good and resists high temperature and high pressure, which can replace the gate valve for use. The operation is easy and efficient as well. Compared with a gate valve, globe valve, or ball valve, this butterfly has lower weight and lower material cost. It is a good choice.
- The product can be used in multi-flow direction projects. The connection is flanged, wafer or BW or Lug wafer.
Installation Direction of Butterfly Valve
Concentric butterfly valves are bidirectional. Double offset and triple offset butterfly valves are also bidirectional but with the preferred flow (pressure) direction, such as flow from the stem side.
Difference between Bidirectional and Unidirectional Butterfly Valve
Unidirectional sealing Butterfly Valve is that when the front of the butterfly plate of the Butterfly Valve is closed, it must face the flow direction of the medium; the medium only flows in one direction, and there must be an arrow indicating the flow direction of the medium on the valve body.
Pay attention to the flow direction of the medium during installation. The two-way butterfly valve is a butterfly plate that can face or face the flow direction of the medium. There is no need to pay attention to the flow direction of the medium when installing, and there is no arrow indicating the flow direction of the medium on the valve body. The force on the stem of the two-way sealing butterfly valve is greater than that of the one-way sealing butterfly valve. In the design, for butterfly valves with the same diameter and pressure, the diameter of the two-way sealing butterfly valve stem is larger than that of the one-way sealing butterfly valve.
Bidirectional pressure generally refers to hard-sealed butterfly valves. Ordinary hard-sealed butterfly valves can only flow in one direction. The reverse flow will cause leakage. Two-way pressure butterfly valves are technological improvements based on ordinary hard-sealed butterfly valves to achieve double-sided flow. Pressure performance.
