Régulateur de pression d'air comprimé
A standalone high-flow pneumatic regulator that reduces fluctuating plant-air pressure to a stable downstream setpoint through a balanced poppet and rolling diaphragm, with a local gauge, locking adjustment and wall bracket.
- 0-12 bar adjustable outlet range
- 380 scfm reference flow for the 3/4-inch size
- Relieving rolling-diaphragm control
Introduction de produit
The Compressed Air Pressure Regulator is a standalone air-line control device for branches that require repeatable downstream pressure without an integral filter bowl, dryer or lubricator. The selected P3Y 3/4-inch BSPP-class configuration uses a die-cast aluminum body, balanced brass/NBR poppet and NBR rolling diaphragm to respond to supply and demand changes. A black non-rising adjustment knob and metal lock ring secure the selected setpoint, while one front-mounted round pressure gauge reports outlet pressure and a steel angle bracket supports wall or machine mounting. The baseline version is self-relieving, allowing excess secondary pressure to vent through the regulator when the setpoint is reduced; non-relieving and reverse-flow/relieving arrangements remain application-selected alternatives. Upstream filtration and condensate removal are separate requirements because this product contains no filter element, bowl or drain.
Key Features
A rolling diaphragm provides a large sensing area for responsive and stable downstream-pressure regulation
The 3/4-inch straight-through body supports high branch flow without combining filtration or lubrication functions
A non-rising black adjustment knob keeps the installed envelope compact while the metal lock ring protects the setpoint
One local round gauge is mounted in a dedicated 1/4-inch gauge port for direct outlet-pressure indication
The second 1/4-inch gauge port is blanked but remains available for an alternate gauge orientation or pressure switch
Self-relieving construction releases trapped downstream pressure when the setpoint is reduced and flow conditions permit
A separate steel angle bracket supports wall or machine mounting without loading the connected air pipe
Préoccupations du client produit
Regulator performance depends on correct flow sizing, supply margin, relief selection, gauge range and clean upstream air rather than the nominal connection size alone.
A regulator sized only by pipe thread may show excessive downstream droop when several actuators demand air simultaneouslySelect from peak simultaneous flow at the minimum available inlet pressure and compare the manufacturer's flow curve at the required set pressure and allowable pressure drop.
Downstream pressure can remain trapped after the adjustment knob is turned downChoose the self-relieving configuration when controlled secondary venting is acceptable, or specify non-relieving construction and provide a separate downstream dump valve where venting through the regulator is prohibited.
Oil, rust or condensate can damage the poppet seat and rolling diaphragm or cause unstable regulationInstall suitable upstream particulate, coalescing and drying stages, then keep the regulator as a separate pressure-control component after those treatment devices.
Operators can unintentionally change a validated machine-air setpoint during routine workUse the lockable non-rising knob and metal lock ring, and reserve the optional tamper-resistant locking arrangement for controlled-access installations.
A poorly placed or incorrectly ranged gauge can hide pressure droop at the actual point of useMount the correctly ranged outlet gauge in the service-facing 1/4-inch port and verify regulated pressure under both static and peak-flow conditions.
Les applications typiques
Stable branch pressure for cleanroom pneumatic actuators and control valvesMachine-side pressure reduction after central compressed-air treatmentControlled air supply to packaging, filling and assembly equipmentPressure management for laboratory instruments and test fixturesReduced-pressure utility air for blow-off, purge and positioning circuitsHigh-flow general pneumatic service where filtration and drying are provided upstream
Paramètres techniques
The selected catalogue-scale identity is a standalone P3Y 3/4-inch BSPP-class gauge-equipped regulator, approximately 182 mm high, 90 mm wide and 94 mm deep. Parker publishes a 17.5 bar maximum inlet pressure, a 0-12 bar adjustment range and 380 scfm (179.3 dm³/s, approximately 10,758 L/min) reference flow for the 3/4-inch size under its stated 10 bar inlet, 6.3 bar set-pressure and 0.5 bar pressure-drop condition. The body provides two opposed main ports and two 1/4-inch gauge ports. The selected image identity fixes one 0-16 bar round outlet gauge in the front port, one blank plug in the opposite port, one black non-rising adjustment knob, one metal lock ring, one rear angle bracket and one integrated secondary-relief path through the relieving diaphragm/bonnet. Actual delivered pressure and flow depend on inlet pressure, setpoint, air temperature, upstream contamination control, piping loss and transient demand.
