Fisher™ 67CFSR-601 67C Series Instrument Supply Regulators

67CFSR-601 is an instrument supply regulator manufactured by Fisher. The following are its technical parameters:

1. **Type**: Stainless steel with filter and internal pressure relief.

2. **Spring case style**: 1/4 NPT.

3. **Adjusting screw**: Square head with closed cap.

4. **Outlet pressure range**: 0 to 150 psig (0 to 10.3 bar).

5. **Drain valve**: Stainless steel, for manual drain only.

6. **Fixed drain**: Yes.

7. **Smart drain internal check valve air setting**: Yes.

8. **Second outlet**: Plugged with pipe plug.

9. **Pressure relief performance**: Low capacity, only for slight seat leakage; if the inlet pressure may exceed the maximum pressure rating of the downstream equipment or exceed the maximum outlet pressure rating of the regulator, other overpressure protection must be provided.

10. **Approximate weight**: 4 pounds (1.8 kg).

11. **Filter Capacity**:

- **Free Area**: 12 times the pipe area.

- **Micron Rating**: Standard polyethylene filter is 5 micron; optional fiberglass filter is 5 micron, optional polyvinylidene fluoride (PVDF) filter is 40 micron, and optional stainless steel filter is 40 micron.

12. **Temperature Capability**:

- **Nitrile (NBR)**: -40 to 180°F (-40 to 82°C);

- **Fluorocarbon (FKM)**: 0 to 300°F (-18 to 149°C);

- **Silicone (VMQ) diaphragm and cryogenic bolts**: -60 to 180°F (-51 to 82°C);

- **Arctic/Cryogenic Construction**: -76 to 140°F (-60°C to 60°C).

In addition, the maximum inlet pressure (body rating) of the 67C series regulators to which the 67CFSR - 601 belongs is 250 psig (17.2 bar) for all models except the 67CS and 67CSR types, which are 400 psig (27.6 bar); the maximum emergency outlet pressure is 50 psi (3.4 bar) above the outlet pressure setting.

The regulator also has some optional configurations, such as handwheel adjustment screw, inlet strainer, structure that meets NACE MR 0175 or NACE MR0103 standards, panel mounting assembly, closing cap, fluorocarbon (FKM) elastomer for high temperature and/or corrosive chemicals, silicone (VMQ) elastomer for low temperature, fixed discharge limit, three-scale outlet pressure gauge, stainless steel stem for valve plug, tire valve or pipe plug for second outlet, smart drain internal check valve, large drip trap with manual or automatic drain, etc.
