Lift Lever option is available. The Mark 95LL Series is suitable for a variety of process and clean utility applications in the bio-pharmaceutical, semi-conductor, and food & beverage industries including: continuous circuit WFI pump deadhead division, bioreactor agitator seal pressure maintenance, large volume fill back pressure release and zero dead leg pressure relief.

The Mark 95s are normally closed valves. When you remove the spring force from a standard Mark 95, any pressure coming into the inlet will open the valve, allowing drainage (i.e. rinse water-CIP-and-SIP condensate). The valve won’t open unless there is pressure coming into the valve. The “LL” option allows users to manually fully open the valve for gravity drainage without pressure. This can be important because all biopharma and parenteral pharma product systems must be drainable. The Mark 95LL Series allows the system to be drainable when not under pressure.
