HALE HAMILTON GLD15MK7/HYD – Hydraulic Regulator
Description
Overview:
Precision Pressure Control for Hydraulic Systems
The Hale Hamilton GLD15MK7/HYD Hydraulic Regulator is part of the 2815 Series spring-loaded regulators, engineered for high-pressure liquid and hydraulic fluid control. Designed for use in industrial systems requiring precise pressure regulation, this model provides reliability and robust performance across a wide range of pressure conditions.
A hydraulic regulator like the GLD15MK7/HYD ensures that downstream components receive fluid at a consistent, controlled pressure, protecting equipment from overpressure damage, improving system stability, and enhancing overall performance.

Construction: Spring-loaded internal mechanism for stable performance and repeatability under load
This regulator uses a spring-loaded design with internal sensing to maintain the selected outlet pressure regardless of fluctuations in inlet hydraulic pressure.
Operating Principle
The GLD15 series like GLD15MK7/HYD employs a spring-loaded diaphragm and valve assembly that adjusts internal flow to maintain downstream pressure at a setpoint. As downstream flow demand changes, the regulator responds dynamically to keep the outlet pressure within tight tolerances, ensuring system stability.
Because of the 0.08 Cv rating, this model is optimized for low-to-moderate flow hydraulic circuits where accurate pressure control is essential — such as test stands, pilot systems, and specialized hydraulic equipment.
Industrial Applications
The Hale Hamilton GLD15MK7/HYD Hydraulic Regulator is suitable for a wide range of hydraulic and industrial fluid applications including:
-
Hydraulic test rigs and calibration systems
-
Process control and instrumentation loops requiring precise downstream pressure control
-
Hydraulic supply manifolds with sensitive equipment
-
Pressure limiting in pneumatic/hydraulic interfaces
-
Liquid pressure regulation in industrial automation systems
Its robust construction and wide pressure range make it a dependable solution in refining, petrochemical, power generation, and heavy machinery systems where stable hydraulic pressure is critical.
Technical Specifications
Parameter Specification Model Hale Hamilton GLD15MK7/HYD Type Spring-loaded hydraulic pressure regulator, 2815 Series Outlet Pressure Range 25–850 psi (1.5–58.6 bar) Maximum Inlet Pressure Up to 690 bar (10,000 psi) Flow Factor (Cv) 0.08 Port Size 3/8″ FNPT Body Material 316 stainless steel Maintenance and Reliability
The GLD15MK7/HYD’s 316 stainless steel body and spring-loaded diaphragm design are built for long-term reliability in hydraulic test and calibration duty, where repeated pressure cycling can wear out lower-grade regulators quickly. Its low 0.08 Cv flow factor is specifically suited to low-flow, high-precision applications rather than high-volume hydraulic supply, so engineers should confirm flow requirements before specifying this model over a higher-Cv variant in the same 2815 Series family.

Confirming the Right Regulator from the Nameplate
Hale Hamilton regulators are built to order in many combinations of body material, pressure range, porting and seal options, and the full model code carries that information. Before ordering a GLD15MK7/HYD as a replacement, check the tag or body marking on the installed unit and compare every character of the model code, not just the series. Also note the serial number, the outlet range stamped on the unit, the fluid it handles and the maximum inlet pressure it actually sees. If the existing tag is missing or unreadable, a photo of the body, ports and bonnet plus the system P&ID reference will usually let the configuration be confirmed.
Installation and Setting Up
- Flush upstream lines and fit a suitable filter; fine particulate is the main cause of seat damage and creep in low-flow liquid regulators.
- Confirm flow direction against the body markings and use thread sealant compatible with the hydraulic fluid, keeping it off the first thread.
- Install a pressure gauge downstream and a relief valve sized to protect downstream equipment in case of seat leakage.
- Start with the adjusting screw backed off, pressurize slowly, then raise the setpoint gradually to the required outlet pressure.
- Check for lock-up at zero flow and confirm the outlet does not creep over a period of time before placing the circuit in service.
Troubleshooting Common Issues
Outlet pressure creeping upward
Usually indicates contamination or wear on the seat. Isolate, depressurize and inspect the seat and poppet; replace soft seals with the correct service kit rather than generic parts.
Unstable or hunting outlet pressure
Check for trapped air in the hydraulic circuit, undersized downstream volume, or a setpoint at the extreme end of the spring range. A different spring range may give more stable control.
External leakage
Inspect port connections and bonnet seals. Confirm the seal material is compatible with the fluid in use, especially where fire-resistant or synthetic hydraulic fluids are involved.
Applications in Oman and the GCC
High-pressure liquid regulators of this kind are used on wellhead control panels, hydraulic test benches, chemical injection skids and valve actuator supply systems across Omani oil fields, GCC gas plants and offshore facilities. The 316 stainless steel body suits the hot, humid and saline conditions common along the Gulf coast.

About brand
High-pressure gas and hydraulic control is the field Hale Hamilton has worked in since 1947, from its base in Uxbridge, United Kingdom. The company designs valves and pressure regulators for naval and industrial duties where pressures are far above ordinary plant utility levels. Seven Star LLC lists Hale Hamilton regulators and sources them for users in Oman who need a like-for-like replacement of a unit already fitted to a skid, test bench or gas system.
Hale Hamilton regulator listed here
The item on this page is the GLD15MK7/HYD, which the manufacturer catalogs as the GLD15 Mk7/Hydraulic in its Series 28 family of spring-loaded regulators: a two-port, stainless steel bodied, panel-mounted unit for hydraulic service. The suffix after the slash matters. A regulator built for hydraulic fluid should not be swapped with a gas version on the strength of a similar code, because seals and trim are selected for the medium.
Ordering Hale Hamilton valves: what we need
Please send the full type code and the serial number from the label or body stamping, the inlet pressure, the required outlet pressure span, the fluid, the port connections and any cleaning or material requirement. Drawings or a parts list from the original equipment builder help a great deal.

The spring and diaphragm system automatically adjusts the valve position to maintain the set outlet pressure, offering fast response and stable control without external power.
Is the body material important?
Yes — the 316 stainless steel body ensures excellent corrosion resistance for hydraulic and process fluids, extending service life in challenging environments.
