当前位置：首页 >> >>Special alloy valvePneumatic high-pressure small flow control valve has the advantages of small volume, light weight, high performance, for precise micro flow control. For example, in the fine chemical industry, its use of flow and pressure of micro controlling precision of scientific research institution. The design of the valve body pressure up to 32MPa. Can choose the moving film mechanism or electric actuator spring gas.
Pneumatic high-pressure small flow control valve technical parameters and performance:
The body part:
| The valve type: | straight through valve body forging |
Nominal diameter: | DN5、8、10、15、20、25mm |
| Nominal pressure: | PN 1.6、2.5、4.0、6.4、10、16、20、32 Mpa |
| CLASS 150、300、 600、900、1500 Lb | |
| JIS 10K、20K、30K、40K | |
| Connection: | Thread: (applicable to 1 "below) |
| Welding：SW、BW | |
Flange focal distance: | In accordance with IEC 534 |
The valve cover form: | The body of a body |
The filler: | V type Teflon, flexible graphite packing etc. |
A seal. | The metal clip graphite gasket, PTFE gasket |
Actuator: | Pneumatic: multi spring actuator |
Electric: 3810L series, PSL series |
Valve parts:
| Valve type: | single seat plunger |
| Flow characteristics: | percentage, linear, quick opening |
| Within the pieces of material : | standard material combinations and see Appendix using temperature, pressure range |
Note:
Configuration 1, above the standard, the seat of metal on metal, PTFE soft seat is optional VI level seal. Can also provide with hardened valve Stalin Levin alloy coating in pieces. According to the specific use of temperature, we have a more rational choice of bolt and nut.
2, the PTFE V standard ring valve stem packing is also can use flexible graphite, graphite packing a equipped with elongated valve cover can be used for temperature more than 232 degrees (450 degrees Fahrenheit).
3, standard body material is carbon steel and stainless steel, can also provide a variety of alloy material for high corrosive applications.
