Description

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 (proportional valve solenoid) 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 (solenoid control 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 valveThere are different ways of proportionally controlling fluid flow rate. Using a proportional control solenoid valve, or using a stepper-controlled proportional valve.

 

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:

Moisture susceptible? Yes No

FAQ
1. What is the recommended filter size for air entering the proportional control solenoid valve?
A. In order to prevent dust particles sticking in the orifice, it is recommend to install at least 50 um of filter before the proportional solenoid valve

2. It is difficult to control the proportional solenoid valve, what is the suggested proportional solenoid valve control (solenoid valve with flow control) circuit?
A. KLPV-HP has a maximum power of 14W and voltage of 24V. It is recommended to use PWM of around 1000 Hz to achieve the best results. In case of any doubt, please contact us for further information

3. Do you offer a proportional solenoid valve controller?
A. At the moment we do not offer a proportional solenoid valve controller(proportional control solenoid valve); however, if you need assistant with controlling the proportional solenoid valve, our team will be able to provide suggested circuit for you.

4. Do you offer customized distribution block and control?
A. We do provide customized service for the distribution block and control manifold for our KLPV-HP manifold.
