Hydraulic Pressure Regulator

A hydraulic pressure regulator senses downstream pressure and adjusts valve opening to maintain the set outlet pressure. When outlet pressure rises above the set value, the regulator restricts flow or vents (depending on design). When outlet pressure drops, it opens to allow more flow. This automatic balancing action ensures stable output pressure under varying operating conditions.

A self-venting hydraulic pressure regulator automatically releases excess downstream pressure through a vent mechanism when the set pressure is reduced. This is highly useful because it allows safe pressure reduction without manually bleeding the system, improving operator safety and reducing downtime during adjustment.

Petronash hydraulic pressure regulators are designed for high-pressure applications with:
Max inlet pressure: 690 Bar / 10,000 PSI

This makes it ideal for high-pressure hydraulic lines used in oil & gas and industrial applications.

Petronash regulators support multiple set pressure ranges such as:

• 0 – 15 Bar(g)
• 0 – 276 Bar(g)
• 0 – 414 Bar(g)
• 0 – 690 Bar(g)

This makes it suitable for low, medium, and high-pressure hydraulic applications.

A piston-sensed design offers:

• high safety and reliability
• stable pressure sensing
• consistent performance even in harsh service
• better control under high pressure conditions

Petronash regulators use piston-sensed design to ensure accurate regulation and long service life.

Hydraulic pressure regulators are widely used in:

• hydraulic power packs (HPU)
• wellhead control panels (WHCP)
• accumulator charging circuits
• offshore hydraulic panels
• test benches and pressure testing systems
• chemical injection / hydraulic skids
• hydraulic control circuits in process plants

They are essential for controlled pressure reduction and stable hydraulic performance.

Petronash hydraulic pressure regulators include a:
Hardened stainless steel seat

This offers excellent wear resistance, especially in harsh applications where high pressure, frequent adjustment, or contamination may occur. It improves reliability and reduces maintenance.

The tapped drain port provides a convenient way to:

• enable downstream pressure reduction adjustments
• assist in venting and controlling changes safely
• improve ease of installation in hydraulic circuits

It supports better control and safer operation during pressure setting changes.

Petronash regulators are available with:
Process connection size: 3/8” NPTF / 1/2” NPTF
Vent port connection: 1/4” NPTF

This makes them easy to integrate into hydraulic panels and packages.

Petronash design focuses on compactness and easy integration through:

• compact build and economic design
• panel mounting ring for quick mounting
• load bearings and impact hand knobs for easy low-torque adjustment

This makes it practical for control panels and skid mounting.

Cv indicates the flow capacity of the valve, which helps in selecting the right regulator for flow requirement.

Petronash flow capacities:
Main Valve: Cv = 0.06
Vent Valve: Cv = 0.08

This ensures stable flow control even in high-pressure hydraulic circuits.

Petronash regulators are engineered for safety and performance, offering:

• high inlet pressure handling up to 690 bar / 10,000 PSI
• self-venting design for safe pressure reduction
• piston-sensed mechanism for stable regulation
• hardened stainless steel seat for longer life
• compact and panel-ready installation design

This makes Petronash a preferred supplier for critical hydraulic systems.
