2. Standard thickness as DIN

ZJCLV valves are designed both standard thick on body and flanges, so reliable for exposure shell performance and pressure resistance as 1.5times than the standard pressure so for long time usage.The valve weight is more than standard. Note: many cheaper valves from other companies always reduce the body thickness to save cost. So it is important to check not only the flange thickness but also the valve weight too simply to difference the good and bad valves.
