OS & Y Gate Valve API600 Class150 4inch

Our gate valve class150# 4inch are popularly ordered by customers.

Due to its high quality and competitive price as bellow characteristics:

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.Thickness standard Body

The carbon steel body, not easy broken, high temperature resistant, reliable anti-exposure performance, Standard thickness flange connection, good pressure resistance; Standard size flange, convenient replacement, Strong versatility.

3. Paint- Spray painting process

Strong corrosion resistance.

4. OS&Y, outside screw and yoke

Well-made, convenient and durable, Strong versatility, Sophisticated process,   precision production.

5. BB, bolted bonnet

Thickness standard, perfect quality, API Specification(the international specification , used in the important industrial pipeline), strict standard, Whole-process quality control, Copper core iron.

6. Flexible wedge, fully guided

Better airtightness. Flexible wedge can fully compensate for seat surface distortion and valve body deformation due to pipe stress.

7. Renewable seat rings

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

8. Forged T-type stem

Strong hardness,, graphite packing sealing, quality guarantee, (thickening the valve stem, the valve stem nitriding treatment, strengthens the hardness, prolongs the life, prevents the valve stem to blow out).

9. 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

Our gate valve WCB class150# 16'' is API standard, well, we accept non - standard customized according to

requirements.
