API Gate Valve Class150 6inch stainless steel CF8M Trim10

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

This valve is designed with OS&Y( outside screw & yoke as rising stem type),  which 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.

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

Anti-blow out valve stem design with a cone type sealing which will be tight clse with the back seat when fully open.Long-threaded stem nut provides long thread life and allows the handwheel to be removed when the valve is fully open.

6. BB,bolted bonnet

Our 6” 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. Renewable seat rings

Long service life, reliable sealing. Flexible graphite packing, good sealing

8. Rising stem handwheel

Small torque, easy to open, open and close effort, design beautiful, easy to operate, and standard strict standards. It is completely strict in accordance with the latest API version.
