The PRV12-12-S-0-30 is a high-performance, cartridge-style hydraulic pressure relief valve designed to safely regulate and limit pressure within demanding hydraulic circuits. Constructed with a robust metallic body, it features a hexagonal mounting section for secure, leak-free installation. The size 12 valve configuration incorporates a threaded upper connection for precise screw adjustment, allowing operators to accurately set the desired pressure limits. Supplied with a translucent protective plastic cap over the lower cartridge section to prevent contamination prior to assembly, this valve provides reliable over-pressure protection essential for both mobile and industrial fluid power systems.
