Product Overview

A compact, 3/2-way, normally open solenoid-operated directional valve designed for reliable flow initiation in pilot or small power circuits. Features a normally open configuration (P→A pass at rest) and includes a manual override for testing and emergency operation.

Key Specifications

Type: 3/2-way, solenoid-operated, normally open
Configuration: Spring return, P→A connected at rest
Port Size: NG6
Max Pressure: 315 bar
Rated Flow: 4-8 l/min
Features: Manual override, subplate mounting
Coil Voltage: 12V/24V DC, 110V/230V AC (typical options)
Seals: NBR (typical)

Applications

Ideal for applications requiring default flow in the de-energized state, such as pilot supply circuits, lubrication system start-up, safety release functions, and other normally open control tasks in mobile and industrial hydraulics.

Frequently Asked Questions

Q1: How is the Z2S6A2-6X/ different from the A1 version?

A1: The main difference is the default flow state. The A2 version is normally open (P→A connected at rest), whereas the A1 is normally closed (P→A blocked at rest).

Q2: What is the typical use for a normally open (A2) configuration?

A2: It is typically used in circuits that require a default flow path when de-energized, such as to keep a pilot system pressurized, to maintain lubrication flow, or to hold a safety device in a released state by default.

Q3: Does it include manual operation capability?

A3: Yes, the "-6X/" suffix indicates that the valve is equipped with a manual override, allowing for manual actuation for testing or emergency use.

Q4: What pressure and flow can it handle?

A4: It is rated for a maximum working pressure of 315 bar and a typical flow of 4 to 8 liters per minute.

Q5: In what type of system is this valve most beneficial?

A5: It is most beneficial in systems where it is safer or more efficient to have flow present by default, and where interruption of that flow (by energizing the valve) is used as a control or safety function.
