DELCO ZJHP-Z Pneumatic Threaded Control Valve - Compact Single Seat Design
The DELCO ZJHP-Z is a compact pneumatic single-seat control valve featuring internal threaded connections (NPT/BSP) for quick installation in small-bore pipelines. Powered by a multi-spring diaphragm actuator, it offers the same high precision and sealing performance as flanged models but in a space-saving design, ideal for HVAC, light industrial, and skid-mounted systems.
Features
A space-saving pneumatic single-seat control valve with threaded ends, designed for precise flow modulation in compact piping systems.
✅Compact Threaded Connection: Features precision-machined Internal Threads (NPT / BSP), allowing for direct installation into pipelines without the need for bulky flanges or welding, significantly reducing footprint.
✅High-Precision Single Seat: Utilizes the proven ZJHP single-seat core design to ensure a tight shutoff (Class IV/V leakage) and accurate regulation of flow, pressure, and temperature.
✅Lightweight Multi-Spring Actuator: Equipped with a low-profile ZHA/B multi-spring diaphragm actuator, making the entire assembly 30% lighter than traditional Flanged Control Valves and reducing support structure requirements.
✅Versatile Action Modes: Supports both Air-to-Open (Fail-Close) and Air-to-Close (Fail-Open) configurations to meet critical system safety protocols in the event of air supply failure.
✅Broad Application Range: Perfect for pilot plants, dosing skids, and auxiliary lines handling water, steam, or gas where space is limited but control accuracy cannot be compromised.
