Product Details：
1. Full port body designCompact structure, reasonable design, smooth channel,small flow coefficient. |
 |
2. Standard thickness as GOSTZJCLV 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 designedThis valve is designed with OS&Y( outside screw & yoke as rising stem type), 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. |
 |
4. Bronze stem nut usedZJCLV 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. |
 |
5. Forged steel T type stemWe 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. |
 |
6. BB,bolted bonnetOur DN300 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. |
 |
7. Renewable seat ringsThe valve seat is replaceable, can be arbitrarily combined with the sealing surface material pairing, to meet the requirements of working conditions, extend the service life.
|
 |
8. Rising stem handwheelSmall torque, convenient opening, saving effort in opening and closing, beautiful design, easy to operate. Fully in Strict Accordance with the Latest GOST Version. |
 |
Advantages of flange gate valve:
• Small fluid resistance.
• The torque for opening and closing is small, so it is easy to open and close.
• The medium flowing direction is not restricted, and it doesn’t disturb flowing and reduce the pressure of pipeline.
• Short length structure.
• Good sealing performance.
Zhejiang Chuanglian Valve Co., Ltd., is a manufacturer of valves.
