|Test And Inspection:
1. Full port body design
Symmetry port, good for medium flow. Sophisticated process, precision production. Strong toughness, high pressure resistance, and high pressure and crack resistance of thickness.
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.
3. OS&Y designed
OS&Y( outside screw & yoke as rising stem type) is the most commonly used valve type in the gate valve. It is convenient and durable because this structure is conducive to the lubrication of the stem due to the rod nut of the stem, and the opening and closing degree is obvious, most commonly used in applications. We have another type as a non-rising stem type, and its valve is not visible for small space.
4 Bronze stem nut used
Our ZJCLV valves use real bronze stem nut for long time service life as easy to lubricate and protect stem screws. Or as customer required，we use American Standard ASTM A439-1983 D-2 as D-2 High nickel cast iron products have good corrosion resistance, heat resistance, structural stability, thermal expansion, and non-magnetic properties. It is suitable for important parts in the machinery industry such as valve stem nuts.
5. Forged steel T type stem
We use the standard forged steel stem material as ASTM A182 F6a. It is with high tensile strength, not like that some small factories use bar material with less strength. And more for bars they only welding a little on the stem ends which is not same as our fully made ends so that the cost is about 30% different.
6. BB,bolted bonnet
Our 2” gate 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.
7. Rising stem handwheel
Small torque, convenient opening, Saving effort in opening and closing，beautiful design, easy to operate, strict standard.
