Model: RSN2-SAE
Item Number: 340133-8
Type: Direct-Controlled Pressure Relief Valve (Overflow Valve)
Brand: Germany RICKMEIER (Rickmeier)
Core Function: To limit the pressure in piping systems and protect hydraulic or lubrication systems from overpressure damage. According to DIN EN ISO 4126-1 standard, it is not classified as a safety valve but rather as an industrial valve for precise pressure regulation and stabilization.
Technical Features
Structural Design
Robust and Durable: Adopts a simple and reliable direct-control structure suitable for high-load industrial environments.
Precise Adjustment: The spindle (optional handwheel operation) supports precise pressure setting (range not specified, but the RSNE model in the same series is suitable for scenarios ≤10 Bar).
Dirt Resistance: The sharp control edges between the piston and valve housing design reduce sensitivity to dirt particles in the medium.
Sensitive Response: The piston has a low starting force and acts quickly when the set pressure is reached.
Applicable Media and Operating Conditions
Media Types: Hydraulic oil, lubricating oil (requires lubricity and non-corrosiveness, with low hard particle content).
Viscosity Range: 7–15,000 mm²/s.
Temperature Range:
Nitrile rubber seals: -25°C ~ +80°C
Fluororubber seals (FKM): -25°C ~ +160°C.
Contamination Level: Complies with up to ISO 4406 21/19/17 standard.
Flow Capacity
Maximum flow rate for the RSN series: 40–650 L/min (special models can be extended to 5000 L/min with optional pilot-controlled operation).
