Free Pressure Relief Valve Upgrades

sprinkler riserAGF is giving a free upgrade to our sprinkler risers! For a limited time, all risers ordered with a pressure relief valve will be upgraded to our new 7000L PRV.

The new pressure relief valves were specifically designed for the sprinkler industry and come installed on the riser. They can be locked closed and left in place during hydrostatic testing. Installing contractors will discover that this feature will save significant time and water during installation. AGF is excited to share this benefit with our customers to help you gain efficiencies in the field. Upgrades began shipping the first week in September and will continue until December 2021. Contact an AGF Distributor to place an order for a RiserPACK and take advantage of this promotion.

AGF Introduces Lockable Pressure Relief Valves to Expedite Hydrostatic Testing

MALVERN, PA, August 5th, 2021 —AGF Manufacturing is excited to introduce two new lockable pressure relief valves, Model 7000L and Model 7200L specifically designed for the fire sprinkler industry. These models can be temporarily locked closed to allow for hydrostatic testing without removing the pressure relief valve from the system, saving significant time during installation. They can be ordered standalone or as part of AGF’s products that include pressure relief.

The new pressure relief valves include two metal tabs: “flush” and “hydro.” The “flush” tab can be lifted to quickly flush debris from the valve or, using a standard flow switch hex wrench, temporarily lock the valve open to allow draining through the relief valve. The “hydro” tab can use the same hex wrench to temporarily lock the valve closed for hydrostatic testing with the valve installed in the system. This feature will allow a sprinkler system or a TESTANDRAIN valve with relief valve and drain trim to be completely installed prior to initial system leak testing, greatly speeding up installation.

New Trends in Corrosion and Freeze Protection for Resilient Fire Sprinkler Systems

How can engineers design wet fire sprinkler systems equipped to prevent corrosion and dry systems equipped to prevent freezing? That has long been a question central to code requirements and new product development. Recent innovations have presented a few possible answers to that question. By including new products like air vents, self-draining auxiliary drains in heated cabinets, and flood elimination devices, engineers can design systems better equipped to protect themselves against the common pitfalls of corrosion and freezing.

Sprinkler Systems and Freezing Weather

Prevent Flooding in Your Facility

In freezing weather, dry and pre-action fire sprinkler systems have a major Achilles heel if improperly maintained—the auxiliary drains. Auxiliary drains, also referred to as low-point drains or drum drips, are required on dry or pre-action fire sprinkler systems to collect condensation that forms in the pipes.

When improperly maintained, auxiliary drains break and can cause major facility flooding. The cost to repair and reset the fire sprinkler system itself is negligible compared to the cost of water damage mitigation, potential lost inventory, tenant interruption, increased liability, and increased insurance premiums.

Luckily, understanding attentive maintenance and other available solutions can help facilities prevent flooding caused by frozen auxiliary drains.

AGF Introduces Flood Eliminator for Auxiliary Drains

Flood Eliminator is installed above the outlet of an auxiliary drain AGF Manufacturing is excited to introduce the Model 5900 Flood Eliminator, an attachment that prevents broken auxiliary drains from flooding a facility. The Model 5900 allows condensate water to collect normally in a standard drum drip. Pressurized flow from a failed drum drip automatically trips the auxiliary drain flood eliminator to cut off that flow. This eliminates the flooding and damage that would result from the system’s failure. The Flood Eliminator can be pre-assembled to AGF’s COLLECTanDRAIN auxiliary drains or retrofitted to existing auxiliary drains.

Which States Require Air Vents? NFPA 13 (2016) Adoption Map

NFPA 13 (2016) and later editions require air vents on all wet pipe fire sprinkler systems utilizing metallic pipe. Jurisdictions across the US have been adopting these editions on their own or by reference in an IBC 2018 adoption. This chart shows which states have NFPA 13 (2016) adoption (or later editions) and which states will be adopting soon.

*Please consult your AHJ to confirm local code requirements

AGF’s PURGEnVENT line of manual and automatic air vents make it simple to meet code requirements with flexible installation options. Plus, PURGEnVENT patented air vents help protect your system from corrosion by releasing trapped air.

For questions about NFPA 13 (2016) changes regarding air vents and corrosion or NFPA 13 (2016) adoption, please contact us to talk to a member of our technical staff.

What is K-Factor?

AGF’s TESTanDRAIN and Inspector’sTEST valves come in a range of k-factors to best meet your needs. But what is k-factor?

K-factor helps to calculate the discharge rate from fire sprinkler heads. The K-factor also determines proper orifice sizing. AGF offers a full range of orifice sizes to accommodate any K-factor for all TESTanDRAIN models.

Maintenance Considerations for Dry Sprinkler Systems

As seen in NFSA Tech Notes:

This Special Edition of TechNotes is an annual reissue of the relevant information to winterizing dry pipe sprinkler systems. It was originally written by Mark Hopkins, P.E., Vice President of Engineering for the NFSA and updated by Kevin Hall, P.E., Manager of Engineering Research for the NFSA.

As the temperature continues to drop, it is important to remind building owners and facility maintenance personnel of some important inspection and maintenance tasks necessary to keep their dry pipe systems in good operational condition during the winter months. Building owners and facility maintenance personnel need to recognize that NFPA 25-2020, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems, provides a minimum set of requirements. NFPA 25 section 1.2.1 states:
