III. PRINCIPLE OF OPERATION

A. General:

1. Movement occurs as pressure variations reg-

is ter on the diaphragm. The registering pres-

sure is the inlet, P

or upstream pressure. The

range spring opposes diaphragm movement.

SECTION III

As the inlet pressure drops, the range spring

pushes the diaphragm down, closing the port;

as inlet pressure increases, the diaphragm

pushes up and the port opens.

2. A complete diaphragm failure may cause the

regulator to fail close, and process ﬂ uid will

discharge from the spring chamber vent hole.

CAUTION

II. INSTALLATION

A. General:

1. A diaphragm valve should be installed up-

stream of the regulator.

2. An inlet pressure gauge should be located

ap prox i mate ly ten pipe diameters upstream

and within sight.

3. All installations should include an upstream

relief device if the inlet pressure could exceed

the pressure rating of any equip ment or the

maximum inlet pressure rating of the unit.

4. Flow Direction: Install so ﬂ ow enters through

the side connection and exits the bottom con-

nection.

5. Install with spring chamber (2) in the vertical

up po si tion to allow for proper draining.

I. DESCRIPTION AND SCOPE

Model C-BPV is a self-contained back pressure / relief regulator utilized in sanitary biotechnological process piping

systems and is used to control upstream (inlet or P

) pressure. Inlet and outlet sizes are 3/4", 1", 1-1/2", 2" and 3".

This angle style regulator is only suit able for liquids and gases at temperatures less than 300°F (149°C). Refer to

Technical Bulletin C-BPV-TB for speciﬁ c design con di tions.

CAUTION

This is not a safety device and must not be substituted for a code approved pressure safety relief valve or a rupture disc.

CAUTION

Installation of adequate overpressure pro tec tion is recom-

mended to pro tect the reg u la tor from overpressure and

all down stream equip ment from damage in the event of

regulator failure.
