Introduction: The document introduces high-relief pilot-operated regulators designed for systems requiring high flow, relief, and pressure regulation. These regulators can be installed in inaccessible locations with control regulators in accessible locations.

Specifications: The regulators feature inline mounting with NPTF and BSPP port threads, a diaphragm design, and an inlet pressure of 400 psig (27.6 bar) maximum. The outlet pressure is adjustable up to 250 psig (17.3 bar), with flow rates exceeding 400 scfm and high relief characteristics up to 200 scfm. The pressure gauge ranges from 0 to 200 psig (0 to 14 bar) standard, with an optional range of 0 to 600 psig (0 to 40 bar).

Standard Specifications: The ambient/media temperature ranges from 0° to 158°F (-18° to 70°C). The body and dome are made of zinc, and the fluid media is compressed air. The seals are made of nitrile, and the valve is brass with a glass-filled nylon valve cap.

Applications: Suitable for high-flow rate applications such as steel production, aluminum production, glass bottle production, and blow molding operations.

Flow and Relief Characteristics: Includes charts for various port sizes, indicating the relationship between flow rate and outlet pressure at an inlet pressure of 91.3 psi (6.3 bar).

Accessories: Lists accessories such as the MUFFL-AIR® Silencer and bracket assembly kits, with specifications for port sizes and dimensions.

High-Capacity Water & Particulate Removal Filter: Uses a centrifugal spinning process to remove contaminants from compressed air, featuring various flow rates, easy-to-read gauges, and manual or automatic drain options. Available with SAE and NPT porting options.

Warranty and Cautions: The standard ROSS warranty and cautions apply, with details available on their website.

Overview: Provides technical specifications and operational details for ROSS Controls' High Flow Relief Valve and Reverse-Flow Regulators, designed for pneumatic systems to prevent over-pressurization and manage pressure control efficiently.

High Flow Relief Valve: Prevents over-pressurization in pneumatic systems by exhausting air if the system pressure exceeds the setpoint by approximately 2 psig. Integrated into a circuit with a remotely piloted fill regulator and a pilot regulator. System pressure is adjustable via the pilot regulator, with an example setting of 50 PSIG.

Specifications: The High Flow Relief Valve has a port size of 1 NPT, an inlet pressure capacity of 300 psig, and a pilot pressure range of 0 to 200 psig. Suitable for ambient/media temperatures between 40°F to 125°F and uses compressed air as the flow media.

Reverse-Flow Regulators: Provide pressure control and quick exhaust capabilities, designed to simplify piping by eliminating the need for bypass check valves, reducing leakage and installation time. Stackable for applications requiring multiple regulators.

Applications: Suitable for dual pressure control of pneumatic actuators, downstream regulation of weld guns, and eliminating trapped air issues when supply pressure is exhausted.

Warranty: ROSS products are warranted to be free from defects for one year from the purchase date, covering repair, replacement, or refund at ROSS's discretion, provided the product is returned prepaid and found defective upon examination.
