Masoneilan solutions for reduction of Volatile Organic Chemicals (VOCs) and Hazardous Air Pollutants (HAPs).
EF (Emission Free) Seal
The EF Seal is an emission containment feature that is standard on most
Masoneilan rotary products.
This seal design can be easily field-retrofitted on any existing valve in the field.
It is a simple dual O-ring design that has undergone extensive testing including successful completion of 750,000 full-stroke cycles without failure.
This design offers an extremely costeffective solution for upgrading processes under the guidelines of the various regional and global emissions reduction regulations.
LE (Low Emission) Packing
Masoneilan reciprocating control valves can be equipped with the low emission packing systems for compliance up to Class A ISO- 15848 Helium and Methane performance levels for both international and US EPA customers.
These live-loaded packing systems maintain a constant sealing force within the packing box, providing low leakage performance with minimal field adjustment.
Bellows Seals are offered for applications as a hermetic metallic seal for valve stem interfaces providing zero leakage to atmosphere.
Typical applications include handling of flammable, toxic, or explosive fluids where leakage may cause environmentally unsafe conditions.
The design also includes a leak-off detection port and a redundant packing box for
