The Risks of Adjustable Pressure Relief Valves

Choosing the correct relief valve needs preplanning

Pressure relief valves protect fire sprinkler system components by relieving excess system pressure from supply surges or temperature changes. Since the 2010 edition, NFPA 13: “Standard for the Installation of Sprinkler Systems” has required pressure relief valves to be installed on all wet pipe fire sprinkler systems. But picking the correct relief valve for a specific system does need a little preplanning. Knowing the desired static pressure of the system and reviewing the UL and FM Standards regarding the required operational characteristic of relief valves used on sprinkler systems for guidance, one can deduce the best rating for a relief valve on any system.

Prepare your Low Point Drain for Winter

Preparing for Winter, Sprinkler System Maintenance

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, low point 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, potentially 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 low point drains.

AGF Introduces Ultimate RISERPACK® Kits

Butterfly Control Valve and Check Valve Kits for Preassembled Floor Control

MALVERN, PA, June 1, 2022 — AGF Manufacturing is excited to introduce its new Ultimate RISERPACK Kits. These floor control add-on kits are available for AGF’s commercial steel RISERPACK models 8000, 8011, and 8611. Choose from three Ultimate Kit options. Add a gear-operated, slow-close, butterfly valve with tamper switch, check valve, or both butterfly valve and check valve. With the addition of an Ultimate Kit, the Ultimate RISERPACK is a complete floor control assembly that saves time and money on system installations.

AGF’s RISERPACKs are compact, fully assembled risers. Models 8000, 8011, and 8611 meet NFPA 13 requirements for wet pipe fire sprinkler systems. They feature a TESTanDRAIN Model 2500 or 2511A for system testing and draining. NFPA 13 standards require the addition of a pressure relief valve on all wet systems. All model 8011 and 8611 RISERPACKs include AGF’s Model 7000L pressure relief valve. The Model 7000L has a lock-out feature that facilitates hydrostatic testing without removing the relief valve from the system to help save valuable installation time.

Fire Sprinkler System Freeze Protection: How to Maintain Auxiliary Drains

Fire sprinkler system freeze prevention is vital for facility managers as temperatures drop. Compromised life safety, facility damage, and more plague facilities with poor maintenance plans.

Proper auxiliary drain maintenance is key to preventing freezing on dry sprinkler systems. Facilities can save thousands each winter with these key steps:

      1. Locate Auxiliary Drains
      2. Perform Preventative Maintenance
      3. Use Correct Service Frequency
      4. Simplify the Plan

So how do you maintain auxiliary drains, and what are they? Let’s dive in.

Model 7000L Lockable Pressure Relief Valve Now Available in 200 PSI

Model 7000L Lockable Pressure Relief Valve
AGF’s new Model 7000L lockable pressure relief valve is now available in 200 PSI as well as the original 175, 225, and 300 PSI. Temporarily lock the 200 PSI pressure relief valve closed to allow for hydrostatic testing without removing the valve from the system. This saves significant installation time by eliminating the need for a return trip to install the relief valve after hydrostatic testing. Order Model 7000L standalone or on your favorite TESTanDRAIN, RiserPACK, or pressure relief kit. For a limited time, AGF is upgrading all riser orders with pressure relief to the Model 7000L for free!
 
Model 7000L has a ½” MIPT inlet and FIPT outlet, a bronze body, and a stainless-steel spring. It includes a metal “hydro” tab that can be temporarily locked with a standard flow switch hex wrench for hydrostatic testing. When testing is complete, remove the hex wrench to allow for standard operation.
 
The Model 7200L has a ¾” MIPT inlet and FIPT outlet and is available in 175 PSI.
