Flange ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between class150-2500, working temperature≤600°C, in oil industry, chemical industry, fossil-field power plants.
1. Both design and manufacture are carry out strictly fellow API600 and API602. The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2. Co hard alloy welded sealing surface, which is wearing resistance, erosion proof, abrasion proof and long-lived.
3. The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistance.
4. Class≥900LB, the media cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.
5. There is backward sealing structure in the valve, so the sealing is reliable.
6. The material of the filling and the flange size can be chosen and the matched according to the applications and the requirement of the wier's. That can satisfy all kinds of working requirements.
- Q:Does the relief valve have a gate valve?
- The pressure reducing valve group is composed of an adjustable pressure reducing valve, a pressure gauge, a copper valve, a Y filter, a rubber soft joint, a spring pressure gauge, a pressure gauge, an air valve, a pressure gauge and a bent pipe.
- Q:Can the soft seal gate valve reach 25 kg?
- Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.
- Q:What are the standards for the execution of cast iron dark pole gate valves?
- Standard Specification for cast iron blind rod gate valves:1, design and manufacture: according to the provisions of GB/T12234-892, structural length: according to the provisions of GB/T12221-893, flange size: according to the provisions of JB79 GB/T9112-91314, inspection and test: according to the provisions of JB/T9092-99 GB/T13927-92Drive mode: manual, electric, gear drive;
- Q:What is the standard for ductile iron gate valve set?
- Fujian - mark light - valve for you to answer:Whether it is the next shot or dark bar, directly flanged valves can be installed, usually apply eighth copies, if the industrial pipeline is apply sixth copies, sixth copies to apply separate sets of flanges and bolts (bolts independent fee).
- Q:What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?
- Z15T stands for manual, internal thread connection, dark wedge single gate. The sealing surface is made of copper alloy. The nominal pressure is PN1MPa;Z15W-16T for manual, internal thread connection, dark wedge type single gate, the valve body material is copper alloy, the valve seat sealing surface material directly processed by the valve body, nominal pressure is PN1.6MPa;Z45T/W-10 stands for manual, flange connection, dark wedge single gate. The valve body is made of copper alloy, and the valve seat face material is directly machined by the valve body. The nominal pressure is PN1MPa;Z41T-10 stands for manual, flange connections, plain wedge single gate, sealing surface material is copper alloy, nominal pressure is PN1MPa.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate
- Q:What are the types and product categories of knife gate valves?
- Knife gate valve drive mode:Manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electronically controlled, hydraulic and pneumatic drive. Knife gate shape: bright rod, dark rod two kinds. Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine and so on. Knife gate valve seal: hard sealing, soft sealing, single-sided sealing, double sided sealing and other material seal.
- Q:What valve is z45w gate valve?
- Z = gate valve4 = connection: flange5 = structure form: dark rod typeW = sealing surface material: same as valve bodyDetails: JB/T308-2004 valve model preparation methods
- Q:What does gate z41t-10 150 mean?
- According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
- Q:What is the difference between cut-off valve and gate valve?
- Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
- Q:What's the difference between a soft seal gate valve and a hard sealed gate valve?
- The difference is that the form of the gate seal surface is different.General gate valves are generally leaking, easy to rust and other phenomena. Soft sealing gate valve (elastic seat sealing gate valve), gate material for cast iron lining rubber, overcome the shortcomings of the general gate valve, such as poor sealing, elastic fatigue, easy to rust, etc.. Soft sealing gate valve is a new product of the traditional gate valve.
