REGULATOR BONNET OPTIONS
Standard Bonnet (No Map Bias Fitting)
Captured Bonnet (3/16” Straight Hose Barb Bias Fitting)
Captured Bonnet (1/4” Hose Elbow (Polyflo Tubing Type)
Bias Fitting)
SENSOR PORT (for Inlet Pressure Transducer) OPTIONS
No Sensor Port (standard)
SAE-3 Sensor Port (Note 1)
SAE-4 Sensor Port (Note 1)
Sensor (Installed) - 0.25 to 4.75 Volt Output (Notes 2,3)
Sensor (Installed) - 0.50 to 4.50 Volt Output (Notes 2,3)
1. Regulators with sensor port will be shipped with this
port open.
2. See drawing for electrical connection
3. Sensor output with 5.0 volt DC Excitement for 5000
psig span

REGULATOR COOLANT BOWL OPTIONS
Thermostat
No Thermostat
Coolant connections are for 3/8” (9.5 mm) ID hose.

INTEGRAL PRESSURE RELIEF DEVICE (PRD) OPTIONS
200 PSI (± 40 PSI) PRD
270 PSI (± 60 PSI) PRD - Standard
350 PSI (± 60 PSI) PRD
1. A 200 psi PRD is not recommended for regulator output
pressures above 120 psig.
2. The regulator PRD is not suitable as a stand alone safety
relief valve. Other downstream protection strategies must
be employed for a robust system design.
PRD CONNECTION OPTIONS
PRD Vents to Atmosphere - Standard
1/4” NPT Male Capture Pipe PRD
1/2” Tube Stub PRD
If regulator is located in a hazardous location, a PRD capture
pipe must be used to route discharge gas to a remote
location.
