6″ Gate Valve API600 Standard
|ASTM A216 WCB
|Wedge Disc Material:
|Flange RF as ASME B16.5
|Face To Face:
|ASME B16.10：L = 267mm
|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
This valve is designed with OS&Y( outside screw & yoke as rising stem type), as most popularly used valve type in gate valves. It 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, most popularly used in application. Vise verse, we have another type as non-rising stem type which stem move is not visible which is used for small space.
4. 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.
5. 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.
6. Renewable seat rings
Long service life, reliable sealing. Flexible graphite packing, good sealing.
7. Rising stem handwheel
Small torque, convenient opening, Saving effort in opening and closing，beautiful design, easy to operate, strict standard.
Fully in strict accordance with the lasted API version.
