Manual clamp style butterfly valves only take up 3/4" of line space regardless of the valve size. Think of them more as a clamp that acts like a valve, as they are very quick and easy to install. In most cases, they can be installed into a Tri-Clamp® connection simply by replacing the clamp for the valve. There is no need for clamps, gaskets, or welding; only existing clamp ferrules. Manual clamp style butterfly valves have a low resistance to flow and are gentle to media. They have a finely profiled disc, and allow bi-directional flow. Also, all wetted surfaces are 20Ra or better sanitary finish. GVC Direct offers the Manual clamp style butterfly valves in 316L SS with either Silicone, EPDM, or Viton® seat materials. Be sure to contact us for any special requirements or sizes.
