The Model CV-1F Fire Protection Check Valve is furnished with grooved ends and can be installed using grooved couplings. The Model CV-1F can be installed with ANSI class 150 Flanges utilizing Grinnell Figure 71 flange adapters and also ANSI class 300 Flange Adapters. All Model CV-1F Check Valves have been designed with a removable cover for ease of field maintenance. Valves installed horizontally or inclined (flow up or down) are to be positioned with the cap facing up. Valves installed vertically may be positioned with flow up or down.
The Model CV-2 Check Valves are rubber faced, torsion spring loaded, swing type check valves. They are designed for use in fire protection systems and related equipment, where it is necessary to permit flow in one direction and shut off flow in the reverse direction. The torsion spring loading quickens clapper closure and therefore minimizes the water hammer that can be associated with reverse flow.
The Model BFV-1 Butterfly Valve is specifically designed to provide for efficient control of fire protection water supplies.TheModel BFV-1 is designed to meet the increasing pressure requirements of the Fire Protection Industry with amaximumoperating pressure of 300 psi. Flow may be from either direction, and the valves may be positioned in any orientation. The valve is furnished with grooved ends for use with grooved couplings and can be easily adapted to langed components utilizing Grinnell Figure 71 Class 150 flange adapters. The body and disc construction provides for increased
strength and durability. The Model BFV-1 Butterfly Valve is provided with 2 sets of SPDT Supervisory Switches for use in outdoor and indoor applications. A high strength stainless steel upper stem is provided for dependability. The surfaces at the upper stem and lower trunnion areas incorporate a reduced dynamic torque and anticompression set design to ensure low operating torque and increased seal longevity.
