Concept
Non-return valve LKC-2 is designed for use in stainless steel pipe
installations to prevent reverse flow.
Working principle
LKC-2 opens when the pressure below the valve plug exceeds the
pressure above the plug and the spring force.
The valve closes when pressure equalization has been achieved. A
higher counter pressure will press the valve plug against the seat.
Standard Design
The valve body is in two parts, assembled by means of a clamp ring
and hygienically sealed with a special seal ring. A guide disc and four
legs guide the spring loaded valve plug with an O-ring seal.
The valve is available with welding ends for tubes according to ISO
and DIN 11850.
