Pneumatic Hard Seal Trip Eccentric Butterfly Valve
Features & Benefits
- Hard-seal butterfly valve is a kind of component used to realize the on-off and flow control of pipeline system.
- It has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. In the known butterfly valve technology, the sealing structure is mostly a sealed structure,
- and the sealing material is rubber, PTFE, and the like. Due to structural limitations, it is not suitable for high temperature, high pressure, corrosion and wear resistance industries.
- The existing one of the more advanced butterfly valves is a three-eccentric metal hard-seal butterfly valve.
- The valve body and the valve seat are connected components, and the valve seat sealing surface layer is surfacing with temperature-resistant and corrosion-resistant alloy materials.
- The multi-layer soft stack seal is fixed on the valve plate.
- Compared with the traditional butterfly valve, this type of butterfly valve has high temperature resistance, easy operation,
- no friction when opening and closing, and the seal is increased when the torque of the transmission
- mechanism is increased during closing.
- The sealing performance and the advantages of prolonged service life.
Product Description
Product Description
- All listed output torques are expressed in inch pounds of torque (in. lbs.).
- Charts for available air pressure are expressed in pounds per square inch (P.S.I.).
- FLOWX actuators offer ±5° adjustment in the open and closed positions on DA52 through DA-125 models.
- For all other models, adjustment is in the open position only.
- The closed position is 0° fixed. Optional retrofit kits are available to allow for adjustment in both open and closed positions on the DA-160, DA-200 and DA-270 models.
