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.Fully in strict accordance with the latest API version.

3 OS&Y designed

OS&Y( outside screw & yoke as rising stem type) is convenient and durable as due to the stem nut of the valve stem, this structure is beneficial to the lubrication of the valve stem, and the degree of opening and closing is obvious.

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 API 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.

PS:While pls note some small factories use casting iron stem nut by surfaced with brass as treat such as material grade ASTM A536 80-55-06 which is 50% cost saving but easily to be broken and break stem screw quality to half.

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.
