2.The main technical parameters:
a. Test valve type: Straight-through flange gate valve, check valve.
b. Clamping method: The clamping jaws clamp the back of the flange, and there is no external force on the valve body.
c. Sealing method between valve and blind plate: O-ring seal on the end face, which can observe the leakage position.
d. Pressure test medium: Water or 4-7bar low pressure gas (air or nitrogen).
e. Completed test items: 1.5 times the nominal pressure shell test, 1.1 times the nominal pressure high-pressure liquid sealing test; 4-7bar
Low pressure air tightness test.
f. Test range: DN100-750, see the pressure test range table.
g. Test valve structure length: 762-1295mm.
h. Test valve flange diameter: ∅ 600-985mm.
i. Test valve flange thickness: 26-70mm.
j. The right working plate can be turned 90°, and the left moving frame can be moved left and right.
k. Spacing between working plates: 750-1750mm.
l. Left and right clamping cylinders: 4X∅ 250mm.
m. Maximum clamping force: 400 tons.
