EATON FL/SV/RL/R/D/SEP/8 Pneumatic Control Valve Assembly

Overview

The EATON FL/SV/RL/R/D/SEP/8 is a custom configured multi-function pneumatic valve manifold assembly from Eaton fluid control range. The slash-separated string is a configuration code rather than a standard catalog part number. The suffix /8 stands for size 8 port connection. The code breakdown: FL = Flow Limiter, SV = Solenoid Valve, RL = Relief Valve, R = Regulator, D = Drain, SEP = Separator. This unit integrates flow control, solenoid switching, pressure relief, pressure regulation, drain and gas-liquid separation into one compact assembly for compressed air or inert gas service. It is used for bespoke pneumatic skids, offshore and process equipment, and is stocked as a matched spare for the original system.

Features

The EATON FL/SV/RL/R/D/SEP/8 combines multiple pneumatic functions in a single package, reducing pipe joints and leakage points. The FL/SV/RL/R/D/SEP/8 has an integrated flow limiter for speed adjustment, solenoid valve for remote on/off control, relief valve for overpressure protection, regulator for stable outlet pressure, drain port for condensate removal, and separator for liquid slug removal. The size 8 port matches 1/2" or equivalent tube/thread interface. The manifold body is normally carbon steel or stainless steel, suitable for process, marine and offshore environments. Since this is a build-to-order configuration, direct replacement requires the full configuration string; individual component substitution is not recommended without circuit validation.

Specs

Device Type: Custom Pneumatic Manifold Assembly Model: EATON FL/SV/RL/R/D/SEP/8 Brand: Eaton Configuration: FL (Flow Limiter) + SV (Solenoid Valve) + RL (Relief) + R (Regulator) + D (Drain) + SEP (Separator) Port Size: Size 8 Media: Compressed air / inert gas Max Working Pressure: Application dependent, typical up to 16 bar Mounting: Manifold mounting Operating Temperature: -20°C ~ +60°C Seal: Standard Buna-N or FKM option Status: Custom configured, not a standard off-the-shelf catalog item

Principle

Process gas enters the EATON FL/SV/RL/R/D/SEP/8 manifold and first passes the SEP separator to remove liquid slugs. The gas then goes through the R regulator to set stable outlet pressure, RL relief valve provides overpressure protection, SV solenoid executes remote on/off control, FL flow limiter controls flow rate, and the D drain discharges accumulated condensate. All functions are arranged on a shared manifold to simplify the pneumatic control loop.

Applications

The EATON FL/SV/RL/R/D/SEP/8 is deployed on custom pneumatic control skids, offshore instrumentation air panels, gas sampling systems and process safety auxiliary air circuits. The EATON FL/SV/RL/R/D/SEP/8 is stocked as spare assembly for original equipment replacement. For new projects, the function group can be split into standard individual FRL + solenoid + relief components.
