FS-67CFR-362 Fisher

FS-67CFR-362 Fisher Programmable controller

Product  Description：

The FS-67CFR-362 is an Instrument Air Filter Regulator that features an internal relief valve for overpressure protection. The "CFR" designation indicates that it includes a filter and has an internal relief capability, which is a critical safety feature for protecting sensitive downstream instrumentation. The construction typically utilizes aluminum or stainless steel for the body, making it highly resistant to harsh industrial environments. It acts as the first line of defense for pneumatic instruments by removing moisture and solid contaminants while maintaining a stable output pressure despite fluctuations in the supply pressure.

Product Parameters

• Body Size and Connection Style: 1/4 inch NPT (female) inlet and outlet connections.

• Maximum Inlet Pressure (Allowable): Up to $250 \text{ psig}$ ($17.2 \text{ bar}$).

• Outlet Pressure Range: Typically configured for $0$ to $60 \text{ psig}$ ($0$ to $4.1 \text{ bar}$).

• Filter Rating: Equipped with a standard 5-micron cellulose or stainless steel filter element to remove fine particulates.

• Maximum Emergency Outlet Pressure: $50 \text{ psig}$ ($3.4 \text{ bar}$) above the outlet pressure setting.

• Temperature Capabilities: Standard Nitrile (NBR) version operates from $-20°\text{F}$ to $160°\text{F}$ ($-29°\text{C}$ to $71°\text{C}$).

• Flow Capacity: High-flow design capable of providing sufficient air for multiple instruments simultaneously.

• Gauge Port: 1/4 inch NPT connection available for monitoring output pressure.

Product Advantages

• Superior Stability: The regulator utilizes a unique internal design that minimizes "droop" (pressure drop as flow increases), ensuring that instruments receive a consistent signal even during high-demand cycles.

• Integrated Protection: The internal relief valve allows the module to bleed off excess downstream pressure, which prevents damage to expensive smart positioners if a leak or failure occurs in the regulator seat.

• Compact and Lightweight: Its small footprint makes it ideal for direct mounting on actuators or within control panels where space is limited.

• Easy Maintenance: The filter element can be replaced without removing the regulator from the piping, and the drip well includes a manual drain valve to easily blow out accumulated moisture and oil.

• Durability: The powder-coated finish and robust internal components provide excellent resistance to corrosive atmospheres commonly found in chemical plants and offshore platforms.

Important Considerations and Precautions

• Correct Orientation: The regulator should be installed with the drip well (filter housing) pointing downwards to allow moisture to collect at the drain point; otherwise, the filter will saturate and lose effectiveness.

• Safety Relief Limits: While the internal relief valve provides protection, it is designed for minor overpressure. In systems where the inlet pressure vastly exceeds the downstream instrument's maximum rating, a secondary safety valve may be required.

• Air Quality: Although the 5-micron filter is effective, it is not a substitute for a primary air dryer. Excessive liquid water or oil in the air supply can quickly clog the element and affect regulation.

• Tightening Torques: When installing the NPT fittings, avoid over-tightening as this can crack the aluminum body. Use a high-quality thread sealant rather than excessive force.

• Regular Inspection: The filter drain should be opened periodically to prevent liquid carryover into the downstream instruments.

Product Applications

The FS-67CFR-362 is a staple in any industry requiring precise pneumatic control.

• Oil and Gas Production: Providing clean pilot air for control valves on wellheads and separator units.

• Chemical and Petrochemical: Supplying air to I/P (Current-to-Pressure) transducers and smart valve controllers where air purity is vital for digital electronics.

• Power Generation: Managing the pneumatic actuators for dampers and steam control valves.

• Pulp and Paper: Used in moisture-heavy environments to protect sensitive air-operated machinery from line contaminants.

• General Industrial: Any application involving pneumatic cylinders or air tools that require a specific, stable operating pressure.
