GRINNELL Model B8200 Butterfly Valves are designed for use with the G-MINE PVC Piping System. Available sizes include 2" to 6" (50 to 150mm) diameters. Precision machined grooves in the valve body provide easy alignment of the valve and G-MINE Coupling,allowing for the insertion of the spline to connect the GRINNELL Model B8200 Valve to the G-MINE PVC System. Flow may enter the valve from either direction and valve can be orientated in any direction.

The GRINNELL Model 308 Butterfly Valve provides dependable, long-term service and superior control of fluid flow in piping systems. Flow can be from either direction, and the valve can be positioned in any orientation. The valve is furnished with grooved ends for use with grooved couplings. The Model 308 Valve includes a gear operator with adjustable stops at the open and shut positions.

The GRINNELL Model B302 Butterfly Valve provides for efficient control of on/off or throttling/balancing service, fluid flow, and "bubble tight" shut-off in piping systems. Flow can be from either direction and the valve may be positioned in any orientation. The valve is furnished with grooved ends for use with grooved couplings and can be easily adapted to flanged components using GRINNELL Figure 71 Class 150 Flange Adapters. (Flouroelastomer and EN gaskets are also available)

The GRINNELL Model B680 Butterfly Valve is for use with grooved copper tube (CTS) piping systems. It provides for efficient control of fluid in piping systems and has a 10 position locking lever handle. Flow may come from either direction, and the valve may be positioned in any orientation. The B680 features a bronze body and a disc that is fully encapsulated with EPDM rubber for potable water service.

The GRINNELL Model B333 Large Diameter Butterfly Valve provides efficient control of fluid flow in piping systems. It is a grooved-end bubble tight shut-off valve with end-to-end dimensions that meet MSS SP-67, Table 4 and a mounting pad that meets ISO 5211 for the mounting of power actuators. The valve is capable of bidirectional fluid flow at working pressures to 300 psi (20 bar) and may be positioned in any orientation.

The GRINNELL Model B8101 Low Profile Butterfly Valve provides efficient control of fluid in piping systems and has a rated working pressure of 200 psi (13,8 bar). Flow may be from either direction, and the valve may be positioned in any orientation. The ductile iron body is epoxy-coated to resist atmospheric corrosion. The disc is EPDM encapsulated ductile iron for compatibility with a variety of chemicals and temperature ranges.
