The electric butterfly valve has a small operating torque, which is the smallest of all valves. It is the executive unit of the instrument in the automatic control system. It takes AC220V, AC380V or DC24V power supply voltage as the power, and receives (4
The soft sealing lug butterfly valve adopts cast iron body, the valve plate is also ductile iron, the valve stem adopts SS304 and the valve seat adopts NBR，
The O-ring is EPDM, the size is DN300 and the pressure is PN16
The nominal diameter of double eccentric butterfly valves can be dn100-dn2600, and the engineering pressure can be pn10-pn16. The valve body of this batch of double eccentric butterfly valves is nodular cast iron, and the valve plate is also nodular cast
The function of butterfly check valve is to only allow the medium to flow in one direction and prevent the flow in one direction. Usually, this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc
The butterfly valve requires a DN100 handle wafer center line butterfly valve with a pressure of PN10. The valve body is made of nodular cast iron, the valve plate is made of nodular cast iron, the valve stem is ss410, the valve seat is NBR, and the O-rin
TJL PN10 DN50 wafer type PTFE butterfly valve is exported to Nigeria. This butterfly valve should be used in the chemical industry, because the fluorine lined butterfly valve can be applied to any concentration of acid, reducing agent, salt, oxidant, redu
Recently, TJL received a batch of valve orders, mainly for seawater. The orders include check valves, fluorine lined butterfly valves and u-flange butterfly valves.
