ultra small flow needle valve is a kind of top guide single seat valve, it has a simple structure, good sealing performance, reliable use and so on. The top guide system is effective enough to overcome the small opening shock, effective and long service life. A smaller flow coefficient is chosen to increase the use of the valve. Multi spring pneumatic film mechanism or electric actuator can be selected. The valve is the use of , professional development of a small flow of the operating conditions of a product. The body is small in size and light in weight, and the inner screw thread structure is more convenient to be installed and disassembled. The whole body has the characteristics of small size, light weight, high performance and precise control of micro flow.Does not apply to the medium of the more dirty occasions, adjusting the media containing granular media, should be aimed at the problem of small throttle clearance, pay attention to prevent the occurrence of blocking card phenomenon. Especially suitable for liquid, steam and other media in the mainstream of the regulation. required. Design featuresThe small opening range can be adjusted continuously The top guide structure, anti vibration The valve cone seal, the sealing effect is good Multi word design, good adjustment performance Valve seat spray welding hard alloy, corrosion resistance, long life Small size, light weight, easy to install The actuator mounted interchangeableTechnical parameterBody form Straight through type forging valve body Spool form Non balance type single seat valve Nominal diameter DN8 25 NPS 1/4" 1" Nominal pressure PN1.6 32.0MPa CALSS 150 1500 LB Applicable temperature 196 650 Optional Connection form Flange, Welding, Screw thread Flange distance Meet IEC 60534 Non-standard customization Gland form Bolt pressing type Sealing gasket Metal graphite gasket, PTFE Seal up PTFE, flexible graphite Actuatorï¼?Pneumatic actuator, electric actuator
