Richter – LPV PFA Lined Plug ValveEnquire Now
The Richter LPV fully PFA lined plug valve requires little maintenance and provides on-going trouble free operation, making it an excellent choice for isolation of process liquids, gases and vapours throughout the chemical industry where pumps, tanks, reactors and heat exchangers require reliable positive isolation and where there cannot be any leaks to the atmosphere.
The in-line, easy to access plug adjustment stops media passing the plug and is independent of the stem seal. The interference fit between the plug and lining with its large sealing area provides the primary seal as it totally surrounds the circumference of the plug on the top and the bottom. The tapered plug is solid, PFA encapsulated and moulded and provides in line sealing while the lining on the valve body is minimum 3mm thick using the high quality Richter German process proven over 60 years. Dovetailed locking of the PFA lining in multiple places provides a perfect fit for severe service, cycling actions and vacuum.
The stem seal is the secondary seal as it does not normally see the full line pressure and is both static and dynamic as well as self-adjusting with reverse lip diaphragm that eliminates leakage to the atmosphere.
Full repair and reconditioning facilities are available at our Vereeniging and Durban branches.
