2. Standard thickness as API

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.

Our 16” swing check valves are designed with standard thickness for bonnet with replaceable back seat as ASTM A276 410. More the bolts and nuts on bonnets are also standard. The bolts are full screws as ASTM A193 Gr.B7, and nuts are ASTM A194 Gr.2H. Many cheap factories use the fake B7 as real material A3 in china which is not screws in the middle of bolts and also 2H nuts are not heat treated so to save about 30% cost but reduce the screw strength finally as cost.
