The Model 7000 is a pressure relief valve specifically designed to relieve excess pressure caused by pressure surges or temperature changes in all wet fire sprinkler systems. Model 7000 pressure relief valves comply with NFPA 13 requirements stipulating that a pressure relief valve must be installed on all wet systems and downstream of all pressure-reducing valves. Model 7000s feature a bronze body, stainless steel spring, and flushing handle to remove debris. The Model 7000 can be purchased individually or as part of the TESTanDRAIN Kit with all necessary drainage piping and connections for use with all AGF TESTanDRAIN valves. Pressure relief valves can be installed on a TESTanDRAIN valve without removing the valve from the line or draining the system completely. The 7000 features a 1/2" MIPT inlet and FIPT outlet and is UL Listed and FM Approved. It is rated for 175 PSI Systems. Other Ratings Available: 205, and 250. Please specify PSI when ordering.

UL and FM standards for sprinkler system pressure relief valves require relief valves to operate within a range of their ratings. FM requires a relief valve to OPEN at a pressure no less than 85% of their rating and UL requires OPENING at a pressure no greater than 105% of their rating. Both standards require the relief valves to CLOSE within a percentage below OPEN. Choose the relief valve comparing static pressure to 90% of the relief valve"s rating to determine the estimated minimum OPENING and 80% of the relief valve"s rating for the approximate maximum CLOSING. The relief valve should be installed where it is easily accessible for maintenance. Care should be taken that the relief valve CANNOT be isolated from the system when the system is operational. A relief valve should NEVER have a shutoff valve or a plug downstream of its outlet.

Reliable fire protection valves are built with the designer and installer in mind, helping you protect lives and preserve property in even the most challenging situations.

Reliable valves have been designed and assembled in the United States since 1920 and are suitable to control a wide range of sprinkler systems, including Wet, Dry, Deluge, and Preaction. Reliable valves are available in a wide variety of sizes, inlet and outlet connections, and pressure ratings. Valves are available factory trimmed or enclosed in the Reliable PrePaK valve cabinet.

Reliable valves carry Approvals and Listings from internationally-recognized testing laboratories including Underwriters Laboratories (UL), FM Global (FM), the Loss Prevention Certification Board (LPCB), and VdS.

As a leader in the fire protection industry since 1920, Reliable has built a reputation for manufacturing the highest quality fire protection valves and has assembled the industry’s most trusted distribution network and team of fire protection industry experts.

The Cla-Val Pressure Relief Valves are designed specifically for fire protection pumping systems and are available in a variety of configurations and end connections.

•  50 Series Pressure Relief and Pump Suction Control Valves used in conjunction with fire pumping systems to relieve excess pressure, control pump draw or prevent surge, depending on the configuration and pilot controls.

•  The 55L-60 is a direct-acting, spring-loaded relief valve that can be installed in any position in a fire sprinkler piping system to prevent pressure build-up that could damage the pipeline.

Cla-Val Pressure Relief Valves are not only durable and reliable, but they are also backed by the more than 80 years of control valve expertise and the best customer service in the business.

FPPI Adjustable Pressure Relief Valves: Used in "grid" type and residential sprinkler systems or when pressure relief is required. Adjustable from 75 to 175 PSI*.

The old requirement/standard for the installation of pressure relief valves was only for gridded systems. Since 2010, NFPA 13, Standard for the Installation of Sprinkler Systems requires relief valves for all wet-pipe systems. The current 2013 version of NFPA 13 Section 7.1.2 now states:7.1.2 Relief Valves.

7.1.2.1 Unless the requirements of 7.1.2.2 are met, a wet pipe system shall be provided with a listed relief valve not less than 1⁄2 in. (12 mm) in size and set to operate at 175 psi (12.1 bar) or 10 psi (0.7 bar) in excess of the maximum system pressure, whichever is greater.

The purpose of the relief valve is to prevent excessive pressure build up within the automatic sprinkler system. For example, excess heat can cause the water within the pipe to expand and possibly rupture the pipe, fittings or sprinklers. If most of the air within the piping was relieved, due to the installed relief valve, there would be no air pockets within the piping where the air could expand.

Cla-Val Model 50B-4KG1 (Globe) / 2050B-4KG1 (Angle) Pressure Relief Valves are designed specifically to automatically relieve excess pressure in fire protection pumping systems.  Pilot controlled, it maintains constant system pressure at the pump discharge within very close limits as demands change.

Since 1986, AGF Manufacturing, Inc. has been committed to providing a unique line of quality components for fire sprinkler systems. We strive to maintain a close working relationship with our customers to meet the ever-increasing demands of our industry.

Our entire product line is manufactured to the highest quality and meets or exceeds ISO 9002 standards. Our valves are approved by Underwriters Laboratories and FM Approvals, LLC. This commitment to quality enhances product reliability and end user satisfaction.
