PRODUCT INSTRUCTIONS
Type 70 Pressure Regulator
INSTALLATION:
The Bellofram high-flow Type 70 is designed for air service only. The maximum supply pressure is 250 PSI.
Clean all pipe line to remove dirt and scale before installation is made. Apply minimum amount of pipe compound
to male threads of air line only. Install regulator in air line; body is fitted with a 1/4", 3/8" or 1/2” NPT for inlet and
outlet connections. The words"IN" and "OUT" are cast into body to indicate the direction of flow. Regulator can be
mounted in any position without affecting its operation. Avoid undersized fittings that will limit flow through the
regulator and cause pressure drop downstream. The use of a filter to remove dirt and liquid in the air line ahead of
the regulator is recommended for best performance. If an air line lubricator is used, it should be located
downstream beyond the regulator in order to avoid interference with the regulator performance.
OPERATION:
The Type 70 is a high capacity regulator that provides a uniform output pressure independent of supply pressure
variations.
Before putting the regulator into service for the first time, relieve pressure on the range spring by turning the knob
counterclockwise. To operate, turn the pressure adjusting knob slowly in a clockwise direction until required
downstream pressure is obtained. Turned in this direction, the range spring compresses causing increased output
pressure.
MAINTENANCE:
The regulator is easily disassembled for the occasional cleaning or removal of foreign matter. Before this is done,
however, shut off valve upstream of the regulator to prevent escape of air when regulator is disassembled. There
is no need to remove the regulator from the pipe line; remove the two 8-32 screws on the bottom of the unit and
pull out the pintle assembly. Wash inner valve assembly with solvent exercising care to avoid damaging
diaphragms and valve facings. (Avoid such solvents as acetone, carbon tet, trichlorethlene.) Replace assembly
carefully.
The vent hole in the bonnet should be kept clear. A slight flow of air through this hole is necessary for the proper
operation of the regulator.
TO INSTALL REPLACEMENT PARTS:
1. Order repair kit. See back of this sheet.
2. Shut off air supply.
3. To replace "O"-ring and pintle assembly, see disassembly instructions above under "Maintenance”.
4. To replace diaphragm assembly.
a. Remove knob assembly, (6) 8-32 screws securing bonnet, guide, range spring and diaphragm
assembly.
b. Install diaphragm assembly and other parts in reverse order. Be sure to align bonnet vent hole with
the “IN” port.
