Product Detail: |
|
The Marsh Bellofram Type 50 & Type 50 NACE are reliable, precision filter air set pressure regulators, designed for instrumentation and general purpose use in both standard (Type 50) and corrosive environments (Type 50 NACE). The Type 50 NACE complies with NACE material requirement #MR-01-75 for sulfide stress cracking-resistant metallic materials for oil field equipment.
The rugged design and construction of the Type 50 includes the incorporation of diecast aluminum housings that are finished with epoxy paint for added protection against scratching, weathering and other challenging environments. Careful design and use of quality materials ensure long, trouble-free operation, even in the most difficult of industrial environments. The user-adjustable Type 50 series offers superior pressure regulation vs. flow characteristics, excellent stability, repeatability and built-in filter with dripwell. A rubberized, soft-seat valve stem provides positive shut-off and "forgives" dirt or other foreign matter. An aspirator maintains downstream pressure and compensates for droop when high flow occurs. A gauge port facilitates convenient gauge installation and can be used as an additional full flow outlet. In addition, Type 50 NACE regulators include an easily serviceable and self-cleaning 316 stainless steel mesh filter that can be side, panel, pipe or through-body mounted.

Fluorocarbon Pintle: A special elastomeric pintle used where elements in the supply air, such as flame retardant synthetic lubricants, are particularly destructive to ordinary pintle material.
Non Relieving: Used in applications where it is desirable to relieve pressure downstream of the regulator, for some constant flow applications, and where the gas flowing through the regulator must not escape at the regulator. Non-relieving regulators should not be used for low or no flow applications.
Knob: Option to replace the square head pressure adjusting screw.
5 Micron Filter: Replaces the 40 micron filter supplied with the standard Type 50 for more complete air filtration.
Corrosive Resistant Epoxy Finish: An epoxy paint applied to the body and dripwell of the regulator exterior surfaces to provide increased corrosion resistance. (Standard with Type 50 NACE)
Tapped Vent: Allows installation of plumbing to capture exhaust air. (Standard with Type 50 NACE)
Mounting Bracket: TYPE 50: Steel (dichromate finish) bracket for side mounting.
TYPE 50 NACE: Stainless Steel bracket for side mounting.
Pressure Gauge: TYPE 50: Dual scale 2 in. (50.8 mm) gauges. Ranges include 0-30 psig (0-200 kPa), 0-60 psig (0-400 kPa), 0-100 psig (0-700 kPa) and 0-160 psig (0-1100 kPa). When specified with regulator, the correct range will be supplied.
TYPE 50 NACE: A dual scale, 0-60 psig (0-400 kPa) P/N 625-000-016, or 0-200 psig (0-1400 kPa)
P/N 625-000-018, 2.47" diameter (63mm) stainless steel pressure gauge is available and must be ordered separately. NOTE: Although the case is stainless steel, the internal components are not made of NACE qualified materials.
Tamper Resistant Cover: An aluminum tubular cover placed over a slotted head adjusting screw and screwed onto the bonnet of the regulator with a wrench. Prevents ordinary hand adjustments. Supplied with an o-ring that is designed to seal the adjusting screw threads in capture bleed applications.
Soft Relief Seat: Used in applications where it is desirable to reduce the standard bleed rate from 6 SCFH [0.17 m3hr] to less than 0.1 SCFH [0.003 m3hr]. (Not available with Type 50 NACE)
Fluorocarbon Diaphragm: Diaphragm as well as all seals are made of fluorocarbon elastomer to prevent deterioration from elements in the air supply, such as flame retardant synthetic lubricants normally destructive to standard Buna-N material.
