Johnson Controls, the provider of smart, healthy, and sustainable buildings, introduces the Tyco RM-2 Riser Manifold with Model TD-2 Test and Drain Valve. The UL and UL-C Listed, FM Approved system simplifies installation, testing, and operation for fire protection contractors by providing all the necessary components in a pre-assembled compact unit, including a unique linear shut-off function offering the ultimate sealing design. The RM-2 Riser Manifold is intended for use with wet pipe sprinkler systems and is ideal for commercial buildings with a small footprint, including new construction and retrofit. Maintaining system pressure The linear shut-off function reduces leakage over time due to debris in media The included Tyco Model TD-2 Test and Drain Valve with adjustable pressure relief simplifies operations for contractors and their customers such as water flow alarm device testing and feed main draining. The linear shut-off function reduces leakage over time due to debris in media. Thanks to its plunger-style valve, the durable TD-2 stands up to the wear and tear that typically leads to leaks. The integrated pressure relief valve automatically bleeds system pressure exceeding 175 psi (12,1 bar) to the manifold drain to maintain proper system pressure. The TD-2 Test and Drain Valve also features test orifices equivalent to that of a 2.8K and 4.2K orifice sprinkler and is available in both 1.25-inch and 2-inch sizes. Easy transition arrangement “This ready-to-install, compact valve riser manifold unit provides customers with a fully-integrated solution that saves time and money on the front end while increasing dependability with the ultimate sealing design,” said Gijsbert Van Rooijen, product manager, Johnson Controls. “With a range of sizes from two inches through six inches, the RM-2 provides a cost-effective and easy transition arrangement to control valves and system piping.” The RM-2 Riser Manifold features all the necessary alarms, pressure gauges, and check valve equipment to fully comply with NFPA 13 standards. The manifold may be installed horizontally or vertically for both single sprinkler rises and floor control in high rises. Additionally, all components can be rotated at the coupling joints to customize the product orientation for optimal installation.
Johnson Controls announces the launch of two new TYCO® pressure control valves for fire protection systems: the TYCO® Model RV-1A Pressure Relief Valve and the TYCO® Model PRV-1A Pressure Reducing Valve. The new valves offer simple, low-maintenance solutions for controlling and maintaining optimal water pressure within commercial fire protection systems. Maintains a relatively constant system pressure The TYCO® RV-1A Pressure Relief Valve automatically relieves excess pressure in fire protection systems to maintain a relatively constant system pressure as flow demands change. Its simple design eliminates the need for users to bleed trapped air from the diaphragm chamber. The valve offers users a nominal relief “set pressure” range of 30 to 250 psi (2.1 to 17.2 bar). "With a simple trim configuration and just one moving part, just like the DV-5A, these new valves provide optimal pressure control with minimal maintenance and dependable, consistent operation over time." – Gijsbert van Rooijen, global product manager, Johnson Controls The TYCO® PRV-1A Pressure Reducing Valve reduces a higher inlet pressure to a lower outlet delivery pressure in water-filled pipes. It automatically maintains the outlet "set pressure" (static and residual) within a close range, regardless of fluctuations in the higher-pressure inlet line or varying flow rates. Valves are factory assembled and fully trimmed “We developed both valves using the same diaphragm design as the TYCO® DV-5A deluge valve”, said Gijsbert van Rooijen, global product manager, Johnson Controls. “With a simple trim configuration and just one moving part, just like the DV-5A, these new valves provide optimal pressure control with minimal maintenance and dependable, consistent operation over time.” The RV-1A and PRV-1A valves are UL and ULc Listed and FM Approved. Both valves are factory assembled and fully trimmed. They are available in sizes ranging from two inches to eight inches, with flange-by-flange and grooved-by-grooved end connection options.
