sprinkler safety valve factory

AGF Manufacturing Inc is a solutions provider to the fire sprinkler industry, specializing in manufacturing products that are reliable, versatile, and code compliant. The company was founded on the principles of reliability, versatility, and code compatibility, and has been introducing original products that accommodate the varying demands of the fire sprinkler industry. AGF is committed to continuously improving existing products and introducing new ones to meet the needs of the fire protection industry. The company has a strong commitment to customer service and has a close interaction with the fire sprinkler community. AGF aims to help manage fire sprinkler systems more efficiently by engineering more intuitive products, resulting in more reliable systems that better protect lives and save resources.

Starting in 2016, NFPA 13 requires the addition of one air vent on each wet fire sprinkler system that utilizes metallic pipe to help mitigate internal pipe corrosion due to trapped air. Developed with input from sprinkler fitter contractors and fire protection engineers, the AGF patented PURGEnVENT are UL Listed and FM Approved while being the most compact option on the market. Additionally, PURGEnVENT does not require a drain line, drip pan, or redundant air vents to prevent leaks. AGF offers three automatic air vents, Models 7900AAV, 7930ECA, and 7950ILV and one manual 7910MAV.

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.

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 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.

Designed for use in grid systems or any sprinkler system where pressure relief is required. The Adjustable Pressure Relief Valve can be adjusted from 75-175 psi.

Did you know that Globe"s Universal Manifold Check (UMC) provides an Adjustable Relief Valve factory set at 175psi and field adjustable to 310psi? Cost Savings = Gives engineers many upfront design options while also eliminating the need for the installing contractor to remove the traditional fixed relief valve for mandatory 200psi hydrostatic tests; save time and money.
