Product Overview
The PARKER ZSRA1PP0Z07 (part number 41564) is a precision-engineered pressure sequence valve from Parker’s ZSRA series of modular sandwich-style pressure control valves. Operating on a direct-acting, spring-biased spool principle, this valve is designed to establish a controlled pressure signal that sequences a secondary circuit once a predetermined primary pressure threshold is achieved. As a sandwich plate valve, it mounts directly between a directional control valve and its subplate, eliminating external piping and reducing potential leak points. The ZSRA1PP0Z07 plays a critical role in multi-actuator industrial hydraulic systems, ensuring that clamping, holding, or secondary motion circuits activate only after the primary circuit has reached the required operating pressure.

Engineering Features & Advantages
- Precision Pressure Sequencing: The direct-acting spool design delivers accurate and repeatable pressure signal generation, ensuring reliable actuation of secondary circuits at the exact set pressure for consistent process control.
- Modular Sandwich Construction: The ISO 4401 / CETOP 3 mounting pattern allows direct integration between a directional valve and subplate, minimizing piping, reducing installation time, and lowering leakage risk in compact manifold assemblies.
- Adjustable Pressure Setting: An external set screw with locknut enables precise field adjustment of the sequencing pressure, allowing fine-tuning to match specific circuit requirements without disassembly.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and body components providing long service life and stable performance across millions of cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Parker ZSRA series standards, ensuring drop-in replacement without modification to existing manifolds or piping.
Typical Industrial Applications
The PARKER ZSRA1PP0Z07 pressure sequence valve is widely deployed in heavy industrial hydraulic systems where controlled sequencing of multiple actuators is required. Common applications include plastic injection molding machines (clamp-before-inject sequencing), metallurgical presses and rolling mills (
