The Smith-Cooper International 101 series boiler drain valve is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. This valve has a cast iron hand wheel for manual on/off control. It has male National Pipe Taper (NPT) threads for connecting to female threaded pipes, creating a tighter seal than straight threads. The maximum pressure rating is 125 pounds per square inch (psi) for cold working pressure (CWP). This valve meets American National Standards Institute (ANSI) B1.20.1 approval for quality assurance.

Boiler Drain Valves are used for heating or plumbing systems containing boilers or water heaters. These valves offer safe and secure shut-off of boilers.

Smith-Cooper manufactures a wide variety of pipe fittings and valves. The company is headquartered in Commerce, California, and meets relevant ANSI, ASTM, and International Organization for Standardization (ISO) 9002 standards.
