API Forged Gate Valve Class150 1inch A105N

Symmetry port, good for medium flow. Sophisticated process, precision production. Strong toughness, high pressure resistance, and high pressure and crack resistance of thickness.

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.

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. Vise Verse, we have another type as a non-rising stem type, and its valve is not visible for small space.

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.

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.

Our 1” 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.

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

Small torque, convenient opening, Saving effort in opening and closing，beautiful design, easy to operate, strict standard.

Fully in strict accordance with the latest API version.
