2.0 INTENDED USE

Barksdale's pressure regulators are sensitive, pressure-control devices used to maintain a pre-determined

pressure in a hydraulic circuit. The regulated output pressure is controlled by adjusting the spring force by air or

hydraulic motor or manually to balance the hydraulic loading. Design features ensure excellent accuracy,

repeatability and high flow coefficients. This regulator works on Shear-Seal® technology which uses fluid

pressure to maintain a leak-free metal to metal seal.

3.0 PED COMPLIANCE

To ensure that products intended for Europe meet the requirements of PED, it is necessary to determine the

proper PED classification. In the PED, pressure equipment can be classified one of the following categories.

• SEP (Sound Engineering Practice)

• Category I, II, III, IV

3.1 SEP Products

This product falls under SEP category as per PED directive

97/23/EC.

The SEP classification applies to pressure equipment that is not subject to Category I, II, III, or IV conformity

assessment, but must be designed and manufactured with “sound engineering practice” as defined by the PED.

3.2 Product Classification

Use the Table 1 below to find the PED category of a specific product. Due to PED Classification limitations,

some products may not be available at full rated pressures. Be sure to check the PED Product Classification

table for any limitations.
