Laser Cutting Machine

The low pressure proportional pressure regulator can be categorised into
1. low flow
2. high flow
3. economic type

The low flow rate version is ideal for regulating air pressure in a small closed volume, applications include mini cylinder and microfluidics.

The high flow rate version is suitable for dynamic process condition or regulating pressure in a bigger volume container.

The economic type has accuracy of 0.5% F.S, it is also suitable for dynamic process, it is suitable for low pressure control in laser cutting machine.

Series QKL-B1S high pressure low flow electro-pneumatic pressure regulator allows pressure control up to 30 bar ( 435 psi), maximum inlet pressure at 34 bar ( 493 psi). Works in both static or dynamic flow condition without pressure droop.

Resolution can reach up to 5mV. Takes 0-10V, 4-20mA or RS485 signal. Series QKL-B3H I/P transducer provides high pressure high flow version, with flow rate up to 6000 L/min (212 scfm). It is able to reach low pressure in quick response time. Provides feedback signal to monitor pressure output. It is possible to customise pressure range, consult factory for customization.
