The LKC-2 non-return valve is specially designed for use in stainless steel pipe installations to prevent reverse flow.     The valve body is in two parts. These are held together by a clamp ring and hygienically sealed with a special seal ring. It can be mounted either vertically or horizontally. A guide disc and four legs guide the spring loaded valve plug with an O-ring seal, ensuring perfect alignment. LKC-2 valves are available with welding ends for either ISO or DIN connections.
