Purchase now: Winner EP-08W-2A-01-Z-04-H Solenoid Valve
Purchase now: Atlantech Drives provides you the Winner Hydraulics EP-08W-2A-01-Z-04-H. This is the advanced version of the standard EP-08W solenoid valve, featuring a critical safety addition: a Manual Override (indicated by the «H» suffix, typically a Push/Pull knob or Hand operation). Like the base model, it is a 2-Way, Normally Closed (NC) poppet valve for Size 08 cavities, operating on 12V DC. The manual override allows an operator to mechanically shift the valve to the «Open» position during a power failure or electrical fault.
Technical Specifications and Emergency Operation
The manual override is a vital feature for safety-critical systems, such as man-lifts, clamps, or emergency lowering circuits. Even if the battery dies or the 12V signal is lost, a technician can physically actuate the valve to release pressure or lower a load. The valve maintains the high-pressure rating (350 Bar) and low leakage characteristics of the standard series. The «H» option usually adds a knurled knob or a protected pin to the end of the solenoid tube.

Expert Installation Advice: Preventing Accidental Actuation
Safety first. Expert Tip: Valves with manual overrides («H» option) should be installed where they are accessible for maintenance but protected from accidental bumps. If a tool falls on the override knob, it could inadvertently open the valve and drop a suspended load. Ensure the override is only used by trained personnel during «Lockout/Tagout» procedures.
Frequently Asked Questions (FAQs)
Q: Does the override reset automatically?
A: Most «H» style overrides are spring-loaded. You must push/pull and hold to keep the valve open. When you release, it returns to the closed position. Some «Detent» versions twist to lock—verify the specific knob type on the unit.
Q: Can I retrofit the override to a standard valve?
A: No. The manual override is built into the tube assembly and the internal pin. You must replace the entire cartridge if you need to add this feature.
