1.Product characteristics and application:
This test bench is designed and manufactured with reference to
similar products of Germany and GB4981 stabdard,It is suitable for
sealing test of straight-through welded valves and straight-
through flange connection valves , before and after installation.
It is suitable for shell test, sealing test (low pressure sealing
test and high pressure sealing test) and upper seal test (ISO5208)
for GB4981, in order to prevent faulty valves from entering work
Features: simple operation, safe and reliable, sensitive test.
2. Features :
1) Applicable to gate valve,globe valve,ball valve,Check valve and
etc direct-flange connection valves
2) Accessories special sealing disc is applicable to test welded
3) Valve clamping type is up pressure,clamp is through press on the
sides of direct-flange connection valves
4) Standard equips with High and low pressure water pump pressure
systems,gas supercharging is selection

1)Before use, press "pump" first, check motor steering and check
whether the action is accurate and reliable.
2) Clamp valve
a) On the premise of ensuring safety, the valve is hoisted to the
test bench working area.
b) Put the suitable sealing ring in the sealing plate according to
the tested valve.
c) Put the tested valve in place .
d) Open “forward”postion of the "screw forward and backward"knob,
opens "into" position, the screw will quickly move to the end of
the valve end 3-5 centimeters after the stop. According to the
different length of the valve rotation "screw advance and retreat"
"screw forward and back" knob to control the screw to move the
sealing disk to the right position.
e) Press the "top tight" button to clamp the valve. Before the
pressure, the oil cylinder should be determined not to return, if
not returned, should first press the "loose" button to the top
pressure cylinder back.
