The enclosed body construction can also be used in applications where fugitive emission protection is specified. This enclosed PVE/S valve is equipped with a fugitive emission package that includes the stem and body seals to provide a secondary containment of the fluid in the valve and leakage to the outside environment from the valve body. 

The valve body is equipped with a tap in the lower half of the valve body with a threaded AISI 316 plug. Additionally available is a gauge indicating the pressure changes in the valve body. The standard body materials are cast iron/mild steel, aluminum and AISI316.
