FAQs
The 61B2/BU000 uses a standard R1/4 port, enabling direct connection to compatible pressure vessels and pneumatic components. When installing, ensure threads are clean, apply appropriate thread sealing as recommended by Norgren, and tighten to the specified torque to avoid leaks. Mount in a location with minimal vibration, and confirm alignment with inlet and outlet to prevent cross-threading or damage during assembly.
Key specs include a maximum inlet pressure of 16 bar, flow capacity of 4.92 dm3/sec, port size R1/4, and operating temperature from -20 to 80 °C. The brass body provides durability, while the pre-set relief mechanism minimizes unauthorized adjustments. These figures help determine suitability for your line pressures, air flow requirements, and environmental conditions.
Yes, the valve is rated for operation from -20 to 80 °C, which covers many standard manufacturing environments. The brass body offers good corrosion resistance, and the unit’s small, robust construction is designed to withstand typical plant conditions. For extreme environments, verify compatibility with exposure levels and consider additional protection measures around the installation site.
Absolutely. The 61B2/BU000 is designed for direct connection to pressure vessels via its R1/4 port. Its compact form factor and pre-set relief capability make it a practical line-side protection device in automation and manufacturing setups, enabling quick integration with existing pneumatics hardware without extensive adaptation.
The unit’s pre-set, tamper-resistant design reduces the risk of unintended adjustments, lowering maintenance overhead. Brass construction and a simple, direct connection scheme contribute to long service life with minimal upkeep. The low-cost form factor and ease of installation translate to faster time-to-value and predictable protection for air systems.
