We are an authorized distributor of the HAWE SEH 2-2/22 P-G24 proportional speed control valve, part of HAWE's SE and SEH series.
It operates at pressures up to 315 bar and has a flow rate of 120 lpm, used for pressure-independent stepless remote control of the operating speed of hydraulic actuators.
The HAWE SEH proportional speed control valve allows the actual flow rate of the actuator to vary proportionally to an electrical signal (control current) within a specified range.
This range extends from manual remote control adjustment of operating speed, enabling simple acceleration and deceleration, to pre-selected speeds in automatic operating cycles.
The HAWE SEH 2-2/22 P-G24 proportional speed control valve is controlled by a proportional amplifier that maintains a constant current, including the EV1M2 and EV1G1 models, which are readily available at Zhenmian.
For simpler applications, such as pump on/off control, a potentiometer connected in series with a proportional electromagnet can be used.
The key functional components of these pressure-compensated speed control valves are proportional electromagnets, flow orifices, and flow controllers.
are available: ① SE type with a DC flow orifice: Its advantage is that the controlled flow rate Qmin can approach zero; its disadvantage is the large moving mass, which limits its response time.
② SHE type with a pilot-operated flow orifice: Its advantage is fast dynamic control with a short response time; its disadvantage is that due to external oil leakage in the pilot control circuit, a very small flow rate is required.
③ Available in two types: two-way or three-way speed control valves.
④ Individual valve structures are available with pipe connections or plate connections. ⑤ Additional function (three-way valve): Pressure limiting valve used to limit load pressure, arbitrary unloading cycles, etc. ⑥ Additional function (two-way valve): Bypass check valve, forming a bridge circuit for arbitrary flow direction using check valves.
⑦ HAWE PB type proportional throttle valves are used in systems where speed control independent of load is not required, as well as for limiting flow.
Plain language sourcing guide for HAWE SEH 2-2/22 P-G24 proportional speed control valve
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
