Overview
Weir type rubber-lined diaphragm valve is used to change the
passage section and the flow direction of the medium. It has
the functions of diversion, cutoff, adjustment, throttling,
check, diversion or overflow. Valves can be used to control
the flow of fluids such as water, steam, oil, gas, mud,
various corrosive media, liquid metals, and radioactive
fluids.
G41J rubber-lined diaphragm valve is a special type of valve
with a shut-off function. Its closing parts are composed of a
steel disc and a diaphragm made of soft materials (rubber and
fluoroplastics). The inner cavity of the valve cover is
separated to achieve the purpose of cutting off the medium in
the pipe
Applicable temperature:
≤85ºC, ≤100ºC, ≤120ºC, ≤150ºC (according to lining and
diaphragm material)

Test
Lining layer: electric spark detection according to BS6755
standard
Shell Pressure test: PN×1.5
Sealing Pressure test: PN×1.1
Structural features:
Diaphragm valve is a special form of shut-off valve:
1. The opening and closing parts of elastic sealing ensure
that there is no internal leakage;
2. The streamlined flow channel makes the pressure loss
small;
3. There is no stuffing box, so there is no leakage;
4. The valve body and the cover are separated by the middle
diaphragm, so that the valve cover, valve stem and other
parts above the diaphragm are not corroded by the medium;
5. The diaphragm can be replaced and the maintenance cost is
low;
6. The variety of lining materials can be applied to various
media, and has the characteristics of high strength and good
corrosion resistance.
