LKC-2 CHECK VALVE FEATURES


Welded Connection


IMPLEMENTATION

LKC-2 check valve has been designed to prevent reverse flow in stainless steel pipelines.

Operation Principle
LKC-2 valve is opened when the pressure under the plug is more than the pressure over the plug and string strength. Valve is shut off when the pressure is balanced. It is also shut off when there is a balance of a higher counter-pressure. A higher counter-pressure value pushes the valve sealing plug against the valve seat.



Standard Design
The valve body consists of two parts, which are a combined with a clamp ring and a special sealing component that ensures hygienic sealing. Four-pillar, spring loaded valve bears the sealing plug with an O-ring gasket. LKC-2 valve is a welded connect6ion for ISO or DIN norms.



Standard Welding
Material.................................................: AISI 304 stainless steel or AISI 316L
Sealing Components.............................: EPDM
Surface Quality .....................................: Semi-lustrous

Valve can be suppled as welded connection in compliance with ISO2037 or DIN 11850 norms. The pressure difference required to open the valve when it is vertically installed on the pipeline is approximately 6 kPa (0,06 bar). (see Figure)


Maximum product pressure ........................ : 1000 kPa (10 bar)
Maximum temperature ................................ : 140 °C (EPDM)
Minimum temperature ................................. : -10 °C



OPTIONAL MATERIAL QUALITIES
A) Sealing component coming into contact with fluid Nitrile (NBR) or viton (FPM).

Please indicate the following specifications when ordering.
• Gauge
• Material Quality, AISI 304 or AISI 316L
• Please indicate if the gasket is not standard EPDM.
