JL300-H4 / Fluorine Lined Check Valve

Check valve is an automatic valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the reverse flow of the medium

FEATURES:

1.Swing Check Valve
The main models include: fully lined JLH44F46, JLH74F46 single disc swing series, and JLH76F46 double disc swing series. Their structural forms are: the valve disc rotates and opens around the (pin) shaft outside the valve seat to prevent shut-off backflow.
The characteristics of JLH44F46 and JLH74F46 check valves are: the (pin) shaft and valve disc are designed as a whole, all lined with FEP, embedded in a special groove formed between the valve body and bonnet, with flexible opening and closing, and reliable sealing. In addition, the characteristics of JLH72F46 and JLH76F46 check valves are: in addition to the valve body and valve disc, the return spring is also all lined with corrosion-resistant fluoroplastic, and the reasonable design of the spring enables the valve disc to generate sufficient sealing pressure in the low-pressure area, ensuring the reliability of the valve sealing.
2.Lift Vertical Check Valve
The main models include fully lined JLH40F46, JLH42F46, and JLH72F46 lift type vertical check valves. Among them, JLH40F46 is a new type of structure with a hemispherical valve disc. Their common feature is that the fluorine lined valve disc moves up and down along the shaft of the valve body passage.
3.Lift Check Valve
The main models include: fully lined JLH41F46 straight lift check valve, which has the structural feature that the fluorine lined valve disc moves up and down perpendicular to the inlet and outlet shaft of the valve body.
