Material Pressure Relief
This document outlines the procedures and components involved in material pressure relief for barrel pumps. The primary function is to prevent segregation of base oil and thickener in non-pressure-stable media, such as oil separation, after the pump is switched off.

Manual Slide Valve HS14
Product Code: DP-K-012-000001
This valve is used for manually shutting off the compressed air supply to the barrel pump and activating material pressure relief. It is compatible with models FP015, FP045, FP045-T, FP050, FP050-T, FP200, FP200-T, and FP200-S.

Switch-On/Pressure Build-Up Valve HEE-⅜
Product Code: DP-K-012-000002
This valve is used for shutting off the compressed air supply via station or line control, deactivating the barrel pump, and activating material pressure relief. It is also compatible with the same models as the manual slide valve.

Pneumatic Ball Cock
This component is used for controlled shut-off of the material line. It comes in various types and variants:

• Double-acting
• Spring-closing
• Spring-opening

Variants include:

• DP-K-008-000001: KH14HD P, double-acting
• DP-K-008-000002: KH14HD P FO
• DP-K-008-000003: KH14HD P FS
• DP-K-008-000004: KH38HD P, double-acting
• DP-K-008-000005: KH38HD P FO
• DP-K-008-000006: KH38HD P FS

Abbreviations used include KH for ball cock, P for pneumatic, FO for spring-opening, FS for spring-closing, with size specifications of 14 for G 1/4" and 38 for G ⅜”.
