A complete line of Steel Isolation Valves (SIV) has been designed to provide flexibility and performance when used in any refrigeration system. The SIV products feature a unique design with a flexible three-port configuration that allows easy access to any service port, no matter where the valve may be mounted in the system. Each SIV has dual ports on both sides of the valve that remain open during normal operation, and can also be used with pressure switches or gauges as required within system operation or service applications. The SIV’s top service port is completely isolated when the stem is full back-seated, enabling it to be used for pressure readings or charging/evacuation when slightly cracked from the back seat. The valves are versatile enough to be customized to meet any design requirement simply by identifying which of the individual ports should be permanently sealed via a special locked-brass seal cap that protects the ports from unwanted tampering and leaks. Additionally, all of the valves’ bodies are specially plated to maximize protection against rust and feature solid-copper connections that allow for easy and quick installation.
