Parker EP series process to instrument valves locate directly onto the process pipeline and facilitate a double block and bleed function for the safe removal of pressure measuring instrument (transmitter or gauge). This is done by isolating the primary block valve, opening the vent to remove the pressure within the instrument , then closing the vent and isolate the secondary block valve. The transmitter (or gauge) can now be safely removed for replacement or calibration in a workshop. The calibrated or replacement transmitter is then re installed and the block valves returned to the open position to resume the instrument function of pressure measurement. The Parker EP series combines 2 block and one bleed valve into a single body. This reduces space, weight, potential leak points and additional costs all associated with the traditional method of combining single flanged block valves to create the double block and bleed function.

The EP series is designed to the EEMUA 182 design code giving the operator and owner assurance of a valve designed to sound engineering practices. Parker offer these valves in many configurations in a wide variety of materials commonly used in industries today. They are manufactured in our UK ISO 9000 compliant facility. The valves are offered with both screwed ends such as NPT Female for direct mount of the instrument or when remote mount is required we offer integral compression fitting ends to facilitate the tubing. The integral compression ends (two ferrule A-LOK or single ferrule CPI) removes the need for NPT, thus removing potential galling, thread tape or sealant, additional leak paths and at the same time reduces the costs associated with buying and installing a separate fitting.
