How to buy the best boiler drain valve 3/4?

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.

This Smith-Cooper International 301 series brass boiler drain valve has a butterfly handle, a male National Pipe Taper (NPT) thread inlet connection, and is used to control flow (throttling) while draining a tank. The valve body and seat are constructed of brass for higher corrosion resistance than steel, its inlet connection is male NPT for connecting to a female threaded fitting, its outlet connection is male hose thread, and its elbow shape helps liquid drain away from the valve. A manually operated butterfly handle rotates the inside chrome plated brass ball mechanism, which closes with a quarter turn to regulate the flow between the connected pipe and hose, and an O-ring reduces the risk of leakage around the valve stem. The valves maximum pressure is 125 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG). This rising stem boiler drain valve is a type of ball valve and is suitable for use in various tank draining systems.

Ball valves use a spherical disc to control the flow between pipes, tubes, or hoses. Flow is allowed when the hole that pierces the ball-shaped disc is in line with the inlet and outlet of the valve and is blocked when the ball is horizontally swiveled 90 degrees, so that the hole of the ball is perpendicular to the opening of the valve. Ball valves can be referred to as full port or reduced port (also known as regular or standard port) depending on the inner diameter or the valve. A ball valve is full port if the hole of the ball is the same size as the inner diameter of the connecting pipeline (resulting in lower friction) and termed reduced port if the hole of the valve is one pipe size smaller than the pipe, resulting in less flow through the valve than through the shaft of the pipe. Ball valves may have a handle or lever that aligns with the balls position (open or closed) for manual operation. They are primarily used in air, gas, liquid, and steam applications.

Smith-Cooper International distributes pipe, fittings, and valves under its SCI trademark and manufactures valves under the Sharpe brand. The company, founded in 1993 and headquartered in Commerce, CA, meets International Organization for Standardization (ISO) standard 9002.

This Smith-Cooper International 100 series brass boiler drain valve has a handwheel, a female National Pipe Taper (NPT) thread inlet connection, and is used to control flow (throttling) while draining a tank. The valve body and seat are constructed of brass for higher corrosion resistance than steel, its inlet connection is female NPT for connecting to a male threaded fitting, its outlet connection is male hose thread, and its elbow shape helps liquid drain away from the valve. A manually operated handwheel rotates the inside screw mechanism, which lifts and lowers the seat disk to regulate the flow between the connected pipe and hose. The valve body has packing in the stuffing box to reduce the risk of leakage around the valve stem. The valves maximum pressure is 125 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG). This rising stem boiler drain valve is a type of globe valve and is suitable for use in various tank draining systems.

Globe valves control flow rates in a piping system by the lift of a vertical stem and disk, which must be turned to open and close the valve. A seated disc extends into the center of the valve to act as a plug to restrict or open the flow path, depending on how tightly the valve stem is turned. The stem on globe valves can be either rising (moves up as the valve opens) to indicate if the flow is on or off, or non-rising (stem height remains constant when the valve is either open or closed) for use in small spaces. Globe valves are used in various water, gas, air, and steam piping systems that require frequent throttling operations.
