10-2400 PSIG Relief Valve
Description
Circle Seal Controls Model M5162T-1M Relief Valve
Catalog literature: Relief Valves Catalog.pdf 
The Circle Seal Controls model M5162T-1M relief valve provides a combination of absolute leak-proof sealing when closed and virtually maintenance-free dependability in a relatively small, lightweight package.
Features:
- Zero leakage: to 95-98% of cracking pressure
- Positive reseat: reseals dead tight only slightly below the cracking pressure
- Accurate set pressure: valves can be pre-set to required cracking pressure
- Adjustable: interchangeable springs permit change of crack pressure range; tamper-proof adjustment inside of valve
- Excellent flow characteristics: lift ring poppet design allows high flow rates with minimum amount of pressure rise
- No chatter: chatter eliminated through use of friction damping device; damping bars prevent poppet from over-travel at initial cracking thrust; damping load is proportional to spring load
- Minimal maintenance: fluid is not throttled across the seal, which, combined with soft seat and poppet design, prevents seat and seal erosion
- Versatile: vent-to-atmosphere or inline connections; various materials for both body and seals; sizes ranging from 1/8″ to 1-1/4″; PED certifications and CE marking available for most models
