Flow-control relief valve MSCCB series

Product catalog summary

Specifications

Operating Pressure: 350 BAR
Flow: 60 L/min
Response Time - Typical: 2 ms
Internal Leakage: 10 drops/min max to 80% of nominal setting
Temperature Range: -30°C to +120°C (-22°F to +250°F)
Cavity: T-13A
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Features

Approximately 1 drop (0.07 cc) of fluid will pass into the vented spring chamber every 4000 cycles.
Atmospherically referenced valves should only be used where it is impossible to have a drain connection. Over time, these valves may leak externally or allow moisture into the spring chamber.

Operation

The atmospherically referenced, direct-acting sequence valve with a reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) exceeds the valve setting. Additionally, these valves incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of this sequence valve controls the pressure at port 1 relative to the atmospheric vent.

Performance Curve

The document includes performance curves showing the relationship between pressure drop and flow rate for both full sequence and reverse free flow conditions.

Installation Dimensions

Details on installation dimensions and torque specifications are provided, including specific measurements and maximum torque values.

Order Type

Seal-Kits: N = Buna N, V = Viton
