Control valves and regulating valves are the actuators in the automatic control system. By receiving the control signal output by the adjustment control unit, the fluid flow is changed by means of power operation. Its application quality directly reflects the adjustment quality of the system.
Control valves and regulating valves are the actuators in the automatic control system. By receiving the control signal output by the adjustment control unit, the fluid flow is changed by means of power operation. Its application quality directly reflects the adjustment quality of the system. Sealing and abrasion resistance are key considerations in the design of control valves. This is more suitable for tungsten steel valve cores and tungsten steel valve seats produced and processed by cemented carbide materials, which can better meet the extreme harsh working conditions of valves. Application requirements, such as high temperature and high pressure differential special regulating valves, high pressure online detachable ball valves, globe valves, butterfly valves, gate valves, etc., are suitable for electric power, petroleum, natural gas, chemical, coal, metallurgy and other industries.
1. Carbide ball core: SΦ49*φ25*47-45*R30*14-8,
2. Tungsten steel sealing seat: φ52*Φ38*Sφ49*φ24*10,
3. Sealed tungsten steel valve seat: φ79.2*φ75*Sφ76.2*φ56*φ44.5*20.
The tungsten steel valve seat is precisely machined and matched with the carbide ball core sphere, and the sealing part is guaranteed to be tightly fitted to meet the requirements of precision valves under harsh working conditions. Tungsten carbide valve core custom processing control valve tungsten steel sealed valve seat, tungsten steel valve head, tungsten steel valve pair, tungsten steel valve ball are increasingly widely used, and the types and quantities continue to increase. The development direction of the caliber, easy adjustment, long service life and multi-functional valve seat.
In order to meet the control and regulating valves required by more harsh working conditions, our company provides multiple choices of tungsten steel valve core materials. The physical parameters of commonly used hard alloy processed and sealed tungsten steel valve seat materials are as follows:
1. Grain size um: 0.4～2.0
2. Cobalt content Co%: 6-20
3. Density g/cm3: 13.96-14.85
4. Hardness HRA: 86-93
5. Bending strength Mpa: 3200-4500
6. Young's modulus Gpa: 570-620
