What Is the Test and Drain Valve?

A Test and Drain valve (TD) has three main functions: pressure relief, test, and drain. Its multi-function design allows it to perform several functions with fewer parts. It also enables periodic testing of sprinkler systems. In this article, we will discuss how the TD valve works. By learning more about this device, you can better understand its functions. Read on to learn more. Once you understand its functions, you can choose a suitable valve for your needs.

A Test and Drain Valve is a simple device used in sprinkler systems to drain unnecessary fluids. They are typically dual-purpose and feature sight glasses in their bodies. The drained line is not too long and can be drained with a single valve. Before selecting a valve for your system, make sure it has the same diameter as the sprinkler orifice. This will help ensure proper installation.

The Test and Drain Valve is a safety valve that performs the function of a drain and test for wet sprinkler systems. Its heavy-duty brass construction is designed for optimum service life. The valve has a single handle ball valve with three working positions and a sight glass for identifying its operation. When not in use, the valve can be used in full port or 1/2" restricting orifice. The valve is also compatible with NFPA 13D.

The Test and Drain Valve is a safety device that is a key component of a fire sprinkler system. It drains the entire system in the event of a fire, and can be used to check the functioning of an alarm. This device can be installed anywhere downstream of a waterflow alarm. Typically, it is part of a riser assembly. Regardless of where it is installed, the Test and Drain valve should be accessible.

The FD and TD are designed for rapid draining and test functions. The FD Test and Drain Valve offers a 5.6 K-Factor orifice, and is designed to simulate the flow of water from a single sprinkler. Its large sight glass plugs make it easy to visually inspect the water flow. It can also be installed horizontally. AGF Model 1000 TESTanDRAIN is a high-quality single-handle ball valve with a UL and FM-approved label.

A Test and Drain Valve is a safety device used to ensure that the water pressure in a sprinkler system is not too high. It allows for a visual check of active water flow and prevents accumulated water from damaging the compressor. It also features a sight glass to see how it performs after the protective material has been removed. Test and Drain Valve should match the pressure rating of the wet pipe sprinkler system. NFPA 13 requires a working pressure of 175 psi.
