Threaded Solenoid Reversing Valve

I. Product Type and Applications
This is a hydraulic cartridge valve, OE number LSV-08-34-C. It functions as a three-position, four-way hydraulic cartridge solenoid directional valve, designed to control flow direction within hydraulic systems. It is commonly used in industrial applications-such as hydraulic circuits in construction machinery-where reliable directional switching, low pressure loss, and controlled leakage are essential.

II. Operating Pressure and Flow Range

Pressure: Rated for standard hydraulic system pressures, this valve maintains stable internal leakage control between high- and low-pressure chambers under operating conditions, preventing system efficiency loss and overheating.

Flow: It must operate within a defined flow range to ensure proper directional switching. Exceeding this range can affect reliability, so actual hydraulic conditions must be matched accordingly.

III. Response Time and Operating Frequency

Response Time (Directional Switching and Reset):
AC solenoid: typically 0.03–0.05 seconds, with noticeable switching impact.
DC solenoid: typically 0.1–0.3 seconds, with reduced switching impact.
Reset time is generally slightly longer than switching time.

Operating Frequency (Switching Frequency):
Single-solenoid models typically support up to 60 switching cycles per minute, suitable for most hydraulic system requirements.

IV. Durability and Service Life

The valve is supplied as 100% new and includes a one-year warranty. Manufactured with quality components by a supplier with over 15 years of experience, it ensures reliable performance.

Service life depends largely on solenoid type-wet solenoids typically outlast dry types, and DC solenoids generally have longer lifespans than AC.

Hydraulic binding of the spool, especially in high-pressure systems with extended stationary periods, should be avoided to prevent reset failure and extend service life.

V. Key Performance Characteristics

Reliability: The valve reliably switches when energized and resets when de-energized, provided it operates within specified pressure and flow ranges.

Pressure Loss: Due to its small orifice size, pressure loss across the valve can be significant, which should be accounted for in system design.

Internal Leakage: Some internal leakage occurs between high- and low-pressure chambers across working positions. Leakage must be controlled to prevent reduced efficiency, overheating, and inconsistent actuator operation.

Frequently Asked Questions (FAQs)

1. What type of valve is this, and what application scenarios is it suitable for?
It is a hydraulic cartridge valve, specifically a three-position, four-way solenoid directional valve (OE No.: LSV-08-34-C). It is ideal for medium-flow control in hydraulic systems, especially in industrial scenarios (e.g., hydraulic circuits of construction machinery, injection molding machines, and power units) that require reliable commutation, controlled pressure loss, and leakage management.

2. What are the response time (commutation & reset) and operating frequency of this valve?

Response time: AC solenoids have a commutation time of 0.03–0.05 seconds (with larger impact); DC solenoids have a commutation time of 0.1–0.3 seconds (with smoother action). Reset time is slightly longer than commutation time for both.

Operating frequency: For valves with a single solenoid, the maximum commutation frequency is typically 60 times per minute, meeting regular hydraulic system operation needs.

3. What factors affect the service life of this reversing valve, and how can I extend it?
Its service life mainly depends on the solenoid type: wet solenoids last longer than dry ones, and DC solenoids outlast AC ones. To extend life, avoid the "hydraulic clamping phenomenon" of the spool (more likely in high-pressure systems where the spool stays in one position for a long time, increasing clamping force and leading to reset failure). Regular system maintenance and clean oil are also critical.

4. What are the product condition and warranty terms for this valve?
The valve is 100% brand-new and comes with a 1-year warranty. Backed by the manufacturer's over 15 years of production experience and high-quality components, it ensures stable performance in long-term hydraulic system use.

5. What key performance characteristics should be noted when selecting this valve?

Reliability: It commutates reliably when energized and resets reliably when de-energized, but only within specified flow and pressure ranges.

Pressure loss: Large pressure loss occurs when fluid flows through, due to the small valve port opening. This must be accounted for in system design.

Internal leakage: Leakage from high-pressure to low-pressure chambers (at specified pressure) must be controlled to avoid reduced system efficiency, overheating, or actuator malfunctions.

6. What is the standard delivery time, and is custom service available for bulk orders?
Standard delivery takes 5–7 working days. Custom services are provided to meet specific B2B needs, such as batch customization for downstream clients in construction machinery maintenance or hydraulic system parts distribution.
