Fisher ENVIRO-SEAL packing systems offer exceptional shaft sealing capabilities.
These packing systems, available with PTFE or graphite packing material, feature live-loading and unique packing ring arrangements for long-term, consistent sealing performance.
ENVIRO-SEAL packing systems easily install in your existing valves or can be purchased with new valves.
ENVIRO-SEAL packing systems help seal your process to conserve valuable process fluid. The long life and reliability of these systems also reduce your maintenance cost and downtime.
For process control applications requiring compliance with specific environmental protection regulations, the Fisher solution is the unique ENVIRO-SEAL packing system. ENVIRO-SEAL packing systems keep emission concentrations below the 100 ppm (parts per million) requirement set by the Federal Environmental Protection Agency (EPA).
For an excellent shaft seal in applications that are not environmentally-sensitive, ENVIRO-SEAL packing systems may be applied at higher pressure/temperature ratings [103 bar (1500 psig)/-46 to 232C (-50 to 450F) for PTFE design or 207 bar (3000 psig)/-198 to 371C (-325 to 700F) for graphite design]. Such applications offer excellent shaft sealing, extended packing life, and reduced maintenance costs when you compare ENVIRO-SEAL packing systems to standard packing arrangements.
