Page 3: Introduction
Figure 3: RPL-X21 RPL-X-Series OBS Technology’s RPL-X (XHPR) series are high performance pressure regulators for controlling pressure up to 863 bar with AISI 316 and 1035 bar with duplex housing. Depending on internal springs and pressure sensors the regulators reduce the inlet pressure down to meet required output pressure like 345, 690 and 900 bar. -

Installation, operation, and maintenance manual Document: RPL-X-P04-MA-IOM RPL-X-P04-MA-IOM Version: Issue date: 25.01.2022 Extreme pressure drops across regulators must be controlled to avoid critical flow conditions. Operator should be fully conversant with this document before attempting to operate regulator. The valve has an internal bleed valve which offloads pressure if downstream pressure increases due to thermal expansion or similar. -

Installation, operation, and maintenance manual Document: RPL-X-P04-MA-IOM RPL-X-P04-MA-IOM Version: Issue date: 25.01.2022 1.1.3 RPL-X21 The RPL-X21 is a high flow regulator developed for fluid operations. The regulator is designed for 863 to 345 barg (12.500 to 5000 psi) inlet pressure, and a range from 50 to 690 barg (725 to 10.000 psi) regulated output pressure. Extreme pressure drops across regulators must be controlled to avoid critical flow conditions. -

XHPR has been removed. No adjustment during operation is possible. The pressure output is pre-set and fixed by OBS, but the pressure regulation functioning is identical. The spring has been selected for the required pressure range and compressed according to the outlet pressure into the spring housing. The rest of the RPL-X14-F is identical with the original RPL-X (XHPR) regulator and work according to the same principles. -

Installation, operation, and maintenance manual Document: RPL-X-P04-MA-IOM RPL-X-P04-MA-IOM Version: Issue date: 25.01.2022 NSTALLATION The function of the RPL-X-series is virtually unaffected by its orientation. The RPL-X-M-versions (Manually operated) is typically mounted with clamps around the body. Some of the RPL-X-series regulators are available with actuator. -
Page 8: Start-Up
TART IMPORTANT NOTICE: The RPL-X series are manufactured to high precision and with tight tolerances and relies on metal-to- metal sealing in the valve to maintain proper operation. Hence, the cleanliness of connected tubing, fittings, and other auxiliary equipment as well as the hydraulic fluid is of utmost importance to the function and reliability of the regulator. -
