Pilot-Operated Cartridge Relief Valve — Engineering & Design

Construction & Materials

The RDBA-LAN-150-bar is a Parker RDBA pilot-operated cartridge relief valve with a hardened poppet and seat, manual adjustment screw with locknut, and a screw-in cartridge body for cavity mounting. The 150 bar spring stage delivers stable cracking and reseat performance. Parker manufactures the RDBA-LAN-150-bar under ISO 9001 quality management using premium-grade materials selected for the arduous operating environment of Saudi industrial plant. Critical wearing surfaces are precision-finished and treated to resist corrosion and erosion, while sealing systems are specified for compatibility with mineral hydraulic fluids, fire-resistant fluids and filtered compressed air as appropriate to the application. The result is a robust assembly that maintains its performance through extended maintenance intervals, reducing the unplanned downtime that is so costly in continuous-process facilities across the Eastern Province and the wider Kingdom.

Performance & Operating Specifications

Set at 150 bar, the RDBA-LAN-150-bar provides accurate pressure limiting with low override and fast response, protecting hydraulic circuits from overpressure. The poppet design ensures repeatable cracking pressure and tight reseat under the thermal and pressure cycling of Saudi continuous-duty plant. These ratings are verified through Parker's type-testing regime and matched to the 150 bar pressure setting and pilot-operated cartridge relief valve headline specification of the RDBA-LAN-150-bar. In Saudi service, where ambient temperatures regularly exceed 45 degrees Celsius and airborne dust is a constant factor, the RDBA-LAN-150-bar retains its rated performance through generous thermal margins, effective filtration interfaces and proven sealing technology. Selecting the correct variant for the duty cycle, fluid or air quality, and environmental conditions is essential to achieving the published service life, and Razz Middle East's technical desk supports customers through this selection process to ensure the chosen configuration is optimal for the application.

Dimensional & Interface Data

The RDBA-LAN-150-bar screws into the standard RDBA cartridge cavity with O-ring and back-up seals, and is available in line-body housings with SAE/BSP ports for in-line mounting, permitting direct interchange with comparable cartridge relief valves. Standardised mounting interfaces, port threads and electrical connections allow the RDBA-LAN-150-bar to integrate directly into existing Parker and third-party systems, simplifying both new installations and like-for-like replacement of legacy components. Razz Middle East can provide full dimensional drawings, port and thread specifications and mounting details on request to confirm fit before order.

Applications in Saudi Arabia

Oil & Gas — ARAMCO & SABIC

The RDBA-LAN-150-bar is widely deployed across Saudi Arabia's upstream and downstream oil and gas sector. At Saudi Aramco facilities, pilot-operated cartridge relief valves of this class serve on wellhead control, blowout-preventer actuation, drilling and workover equipment, valve actuation and skid-mounted process packages where dependable hydraulic performance is safety-critical. Across SABIC and Sadara petrochemical complexes in Jubail and Yanbu, the RDBA-LAN-150-bar supports circuit protection, pump-discharge relief and pressure-limiting duties on skid-mounted hydraulic packages. The RDBA-LAN-150-bar's proven sealing and corrosion resistance make it well suited to the corrosive, high-temperature conditions found throughout the Kingdom's hydrocarbon processing infrastructure, where equipment reliability directly underpins plant availability and personnel safety.

Construction & Heavy Industry — NEOM, Vision 2030

The RDBA-LAN-150-bar protects mobile and fixed-plant hydraulic circuits against overpressure with a precise 150 bar setting. Within the giga-projects driving Saudi Vision 2030 — NEOM, The Line, Qiddiya and the Red Sea developments — the RDBA-LAN-150-bar is specified on construction machinery, material-handling equipment, mobile plant and fixed industrial installations. Razz Middle East supports EPC contractors with stock availability and technical data that keep these high-profile projects on schedule.

Water & Process Industry — SWCC, Ma'aden

The valve limits system pressure on desalination and minerals-processing hydraulic skids. In SWCC and NWC desalination and water-treatment plants the RDBA-LAN-150-bar serves on pump skids, valve actuation and filtration systems, while at Ma'aden mining and minerals-processing sites it withstands the heavy-duty, abrasive conditions of crushing, conveying and materials handling. The RDBA-LAN-150-bar's durability and serviceability deliver low lifecycle cost in these continuous-duty process environments.

Installation & Maintenance

Install the RDBA-LAN-150-bar in a clean cartridge cavity to specified torque, adjust to the required 150 bar setting under flow and lock the adjuster. Razz Middle East recommends installation by qualified technicians in accordance with Parker's published procedures, with attention to correct mounting alignment, fluid or air cleanliness, and torque specifications. Routine inspection of seals, fasteners and interfaces, together with maintenance of the specified filtration and fluid-condition standards, will secure the full rated service life of the RDBA-LAN-150-bar. Genuine Parker spare parts and seal kits are available through Razz Middle East to support planned maintenance across the Kingdom.
