LKC Non-Return Valve Key Features
Standard Design
The Alfa Laval LKC Non-return Valve consists of a Valve body in two parts, valve plug and spring, assembled by means of a clamp ring and hygienically sealed with a special seal ring. A guide disc with four legs ensures alignment of the spring loaded Valve plug with an o-ring seal. The Valve is available with weld and clamp ends for ISO and DIN tubing connections.
Safe and Reliable Process Protection
Alfa Laval LKC-2 Non-Return Valves are highly reliable Check Valves that ensure single directional product flow through process lines. This provides protection for process equipment that can be affected by reverse flow and prevents pressure surges and/or system shutdown.
Non-Return Valve Range
The standard range of Alfa Laval LKC-2 Non-Return Valves are constructed of standard 304 or acid-resistant 316L stainless steel. Easy to install, the Valves are designed to handle maximum product pressure up to 10 bar and temperatures ranging from -10°C to 140°C (EPDM). For added versatility, these Check Valves are available with either a semi-bright or polished finish, and a variety of welding ends for ISO or DIN connections.
How Alfa Laval Non-Return Valve Works
The spring acts on the Valve plug, keeping the Valve closed until the force from the pressure in the inlet exceeds the force of the spring. If a reverse flow should occur, the spring force and the pressure from the outlet will keep the Valve closed.
