Bushing Valve – BU, BR

The Bushing Valve (BU, BR) is a check valve with a standard bushing housing. The valve is adaptable to many types of service applications. It has very little restriction and produces a low pressure drop. It can be used quite effectively in systems where flow and pressure drop are critical by the use of a reducer coupling. The BU valve also makes an excellent vacuum breaker. The high flow rate insures maximum effectiveness for vacuum breaker service. By reversing the direction of flow it can also be used as a low pressure relief valve.

Connector Valve – CN, CR

The Connector (CN, CR) valve is a check valve with a pipe nipple or connector housing. It is designed to be used in installations where a check valve with male pipe threads are required. The CN valve is adaptable for use as a check valve, vacuum breaker, or low pressure relief valve. Two valves used in combination make an excellent pressure vacuum vent. NPT threads are per ASME B1.20.1. This valve is also available with ISO 7 "R" threads (CR).

Flange Insert Valve – F1, F6, FP

Flange Insert valves are the ultimate check valves in flanged systems. They provide the simplest most economical way to install check valves in a piping system, the valve body automatically positions the valve and holds it in place while bolts are being installed and tightened. All that is required is two gaskets in place of the one normally used in a flanged joint.

Horizontal Vertical Flanged & Drilled Valve – HV

The Check-All Flanged & Drilled (HV) check valve is a one-piece cast body valve with ANSI/ASME B16.5 Class 150 flanged ends. The HV series valve is used when higher flow rates and lower pressure drops are required. The valve is available in sizes 1 through 10 inches and standard materials of CF8M (cast 316 stainless) and WCB/WCC (cast carbon steel). The HV series valve is designed for use with mating ANSI class 150 flanges.

Universal High Pressure Valve – U1, R1

The Universal High Pressure (U1, R1) check valve is a one piece body machined from bar stock with female pipe threads. This valve is normally supplied with a "metal-to-metal" seat. NPT threads are per ASME B1.20.1 and also available with ISO 7 "Rp" threads. (R1). The valve is designed and manufactured for high pressure applications.

Universal Low Pressure Valve – U3, UR

The Universal Low Pressure (U3, UR) check valve is a one piece body machined from bar stock and is designed for minimum pressure drop. The valve is light-weight, compact, and provides maintenance-free dependable service. NPT threads are per ASME B1.20.1 and this valve is also available with ISO 7 "Rp" threads (UR).

Wafer Insert Valve – WV

The Wafer Insert (WV) valve is designed to fit between two mating ANSI flanges. Two gaskets are required, instead of the one normally used. The "drop in" valve body fits inside the bolt circle for quick installation and removal in rigid piping applications where the use of the F1, F6, or FP are not practical. Many valves in this series meet API 594 and/or B16.34 requirements.
