Fisher 67C Regulator | 67CFR Instrument Supply Filter Regulator

The Fisher 67C series is a direct-operated regulator and filter regulator for pneumatic instrument supply. It reduces inlet pressure to a controlled outlet pressure for pneumatic controllers, electro-pneumatic controllers, and other field instruments.

The 67C series works in air and gas applications across process plants. Operators use these regulators for instrument air supply, pneumatic actuator control, and general gas pressure reduction.

The 67C series belongs to the Fisher instrument supply regulator line. It uses a direct-acting diaphragm design to maintain outlet pressure without external power or control signal.

The regulator body supports panel mount installation for control panels and instrument racks. Port sizes cover 1/4 inch, 3/8 inch, and 1/2 inch in NPT or BSP threads to fit different piping layouts.

An internal relief valve protects downstream equipment from overpressure. The Smart Bleed internal check valve releases outlet pressure when supply pressure fails, preventing backflow into the supply line.

• Direct-acting diaphragm design maintains outlet pressure without power or control signal
• 0–150 psig outlet range covers most pneumatic instrument supply requirements
• 45 SCFM flow capacity supports multiple instruments from a single regulator
• 40 micron filter element removes particulates from supply gas (filter version)
• Aluminum or stainless steel body options fit standard and corrosive service
• Panel mount design fits control panels and instrument racks
• Internal relief valve protects downstream equipment from overpressure
• Smart Bleed check valve releases outlet pressure on supply failure and prevents backflow
• Corrosion-resistant fasteners extend service life in plant environments
• Compact body fits tight panel and piping layouts

The 67C series includes these common configurations:

• 67CFR-226: filter regulator, aluminum body, common instrument air service
• 67CFR-239: filter regulator, stainless steel body, corrosive gas service
• 67C (non-filter): standard regulator without filter element
• 67CFR: filter regulator with 40 micron synthetic filter element

Send your required outlet pressure range, port size, and body material. We confirm the correct 67C model before you order.

Century Weiye (Dalian) Control Equipment Co., Ltd. focuses on the supply of Fisher valve positioners. We have accumulated years-long experience in process-control instrument supply. Our business covers project clients across global regions. Local warehouse maintains stock of Fisher valve positioners for prompt shipment upon order confirmation.

Every Fisher 67C regulator order goes through a technical review: model, outlet pressure range, port size, body material. We check these before quotation, not after shipment. Datasheets and inspection documents are available on request. We handle single-unit replacement, spare-part stocking, and bulk project procurement.

Q: What is the difference between 67C and 67CFR?

A: 67C is a standard regulator without a filter element. 67CFR is a filter regulator with a 40 micron synthetic filter element.

Q: What outlet pressure range does the 67C cover?

A: 0 to 150 psig (0 to 10 bar).

Q: What is the maximum inlet pressure?

A: 250 psig for aluminum body, 400 psig for stainless steel body.

Q: Does the 67C require power?

A: No. It is a mechanical direct-acting regulator.

Q: When should I choose stainless steel body?

A: For corrosive gas, high humidity, or washdown environments.

Q: What does the Smart Bleed check valve do?

A: It releases outlet pressure when supply fails, preventing backflow from the downstream side.
