Products
KLPV-HP is a high flow compact size proportional valves series. This non-spool design using a moving part to ensures frictionless performance and a lifespan of up to 1 billion cycles. The internal components are resistant to high and low temperatures up to -196 Celsius, showing the same performance in different environments, suitable for air, hydrogen, oxygen, or liquid nitrogen.
Features
KLPV-HP proportional solenoid valve is available with inline mounting option. Different orifice size from 0.5mm up to 3.5mm is available with different maximum operating pressure. It also features quick response time, high flow, resistant to low temperature, and flexible mounting.
Working Principle
KLPV-HP proportional solenoid valve is a direct acting proportional valve, where the extent of the internal movement of magnet is proportional to the input electric current. It consumes maximum of 14W; the higher the input electric current, the bigger the internal orifice for flow. The internal part is made of stainless steel 316 and it is also ideal for corrosive fluids.
Advantage of proportional control solenoid valve
There are different ways of proportionally controlling fluid flow rate. Using a proportional control solenoid valve, or using a stepper-controlled proportional valve. Here is a comparison of using these 2 methods of controlling fluid flow rate:
