Parker 929891Q Solenoid Valve | 5/2 Way, 1/4" NPT, 24V DC, 3W, ISO-5599/1, Brass

Parker 929891Q solenoid valve specifications. 5/2 way, double solenoid, 1/4" NPT, brass body, 24V DC, 3W, ISO-5599/1 subbase. Part of the P1P series.

Product Overview

The Parker 929891Q​ is a 5/2 way double solenoid pneumatic valve​ from Parker's P1P (Series P1P-5-1/4) product line. It features a five-port, two-position configuration, a brass body with 1/4" NPT ports, and operates on a 24V DC supply. The valve is a direct-acting, double solenoid pilot valve​ mounted on an ISO-5599/1 compliant subbase. The "Q" suffix in the part number may indicate a specific configuration variant, such as a particular coil type or connector. It is designed for precise directional control of double-acting cylinders and actuators.

Technical Specifications

Note: Specifications are based on the Parker P1P series catalog. The "Q" suffix may denote a specific variant; always verify with the latest Parker datasheet.

Key Features

• 5/2 Way Function:​ Controls double-acting actuators (extend/retract).

• Double Solenoid (Memory Function):​ Remains in last energized position when de-energized.

• Direct Acting Design:​ No minimum pressure required; reliable at low pressure.

• ISO-5599/1 Subbase:​ Standardized footprint for easy mounting and interchangeability.

• High Flow Capacity:​ 5.0mm orifice (Cv ~1.3) for good cylinder speed.

• Manual Override:​ Individual push-button overrides on each solenoid for manual testing.

• LED Indicator:​ Integrated LED on each coil for visual status.

• Low Power Consumption:​ 3W per coil for energy efficiency.

• IP65 Rating:​ Protected against dust and water jets when connector is attached.

• Robust Construction:​ Nickel-plated brass body for corrosion resistance.

Port Configuration and Function (ISO 5599/1)

Note: For the 929891Q (Double Solenoid), pilot supply ports (e.g., 12, 14) on the subbase are not used.

Legend:​ ● = Connected, ○ = Blocked/Closed

When both solenoids are de-energized, the valve remains in its last position (memory function).

Electrical Connection and Coil Data

Flow Characteristics

Typical Applications

• Double-Acting Cylinder Control:​ Precise control of cylinder extension and retraction.

• Rotary Actuators:​ Controlling pneumatic rotary actuators for valve operation or indexing.

• Clamping/Pressing:​ Applications requiring a cylinder to hold in the extended or retracted position.

• Automation Machinery:​ Actuation in packaging, assembly, and material handling equipment.

• Process Control:​ Operating pneumatic process valves (via actuators).

• Safety Circuits:​ As part of lock-out or safety interlock systems (with appropriate design).

Important Technical Notes

1. Memory Function:​ This is a double solenoid, 2-position valve. It has no spring return. When de-energized, it stays in its last position. For a valve that returns to a "home" position, a single solenoid, spring return (5/2 or 5/3)​ valve is required.

2. Power Supply:​ Ensure a stable 24V DC (±10%) supply. Use a properly rated power supply and consider inrush current for multiple valves.

3. Pilot Supply:​ This is a direct-acting solenoid valve; it does NOT​ require a separate pilot air supply.

4. Manual Override:​ The manual override buttons are latching. Press to manually shift the valve; pull to release. This is useful for setup and troubleshooting.

5. Exhaust Ports:​ Ports 3 (R) and 5 (S) are exhaust ports. They should be piped to a muffler (silencer) or to a safe location, especially in clean or noise-sensitive environments.

6. Mounting:​ The valve mounts to an ISO-5599/1 subbase. Ensure the subbase is properly secured and the valve is snapped into place.

7. Media:​ Use clean, dry, filtered compressed air (5µm or better). If lubricated air is used, do not stop lubrication.

8. Electrical Connection:​ Use the correct DIN 43650 Form A connector to maintain the IP65 rating. Ensure polarity is correct for DC operation.

9. Heat Dissipation:​ The 3W coil generates heat. Allow for adequate ventilation, especially when mounted in an enclosure with other heat-generating devices.

Note: This data sheet provides general specifications for the Parker 929891Q solenoid valve. For complete installation guidelines, wiring diagrams, performance curves, and safety information, consult the official Parker P1P Series Catalog​ and technical manuals. Always verify the exact model number, voltage, and function against your application requirements.
