的详细介绍 |
Far superior in performance when compared to the commonly usedpoppet type valves, the rugged Series 63 delivers long,trouble-free service.
FEATURES
Bray Controls offers the high flow Brayline Series 63 SolenoidValve. The compact, modular, pilot operated spool control valve isconvertible from 3-Way (3/2) to 4-Way (5/2). These units can beused with either spring return or double acting actuators whereon/off electrical operation is required. Three standard coilhousings/connec-tors are available: General Purpose Watertight(NEMA 4,4x) and Explo-sion Proof (NEMA 4,4x,7&9) units have1/2" NPT connections, and IP65 DIN units have cable gland PG9connectors. All housings types are offered with single or dualcoils. The coils are UL recognized and CSA certified. All Series 63solenoids carry the CE mark.
MANUAL OVERRIDE
Each unit contains as standard a mechanical manual override locatedon the solenoid valve block. In the event of electrical powerfailure, over-riding is simply a matter of rotating the manualoverride screw which will divert the air from one chamber of thepneumatic actuator to the other.
DIRECT MOUNTING
Meeting NAMUR (VDI/VDE 3845) standards, all Brayline Series 63solenoid valves direct mount to the integral porting system of BraySeries 92/93 pneumatic actuators. No external piping is required.Bray’s direct mounting permits quick and simple field installation.
SERIES 55 SPEED CONTROL
Speed controls that allow independent control of speed in bothdirections of actuator travel are optionally available.
CONVERTIBLE 3 & 4 WAY
Solenoid is shipped with both 3-Way (marked 3/2) and 4-Way (marked5/2) flow plates, flow gaskets, O-rings that mount between flowplate and actua-tor, and mounting bolts.
OPTIONS
The Series 63 is available in the following options: stainlesssteel housings, low-powered units and intrinsically safe units.Intelligent, digital Bus solenoids are offered in DeviceNet andProfibus-PA protocols, and AS-I Interface sole-noids with IP65DIN/PG9 cable gland connectors are available. All direct mount toBray pneumatic actuators.

SPECIFICATIONS
COIL HOUSINGS
Three standard coil housings are offered. The watertight (NEMA 4,4x) housing offers a molded and potted coil with UL recog-nizedcomponents and CSA certification. The watertight and explosionproof (NEMA 4,4x,7,9) housing is ULlisted and C.S.A. certified forhazardous locations Class I, Div.1 (Groups A-D) and Class II, Div.1(Groups E-G). The IP65 DIN housing has UL recognized components andCSA certification.
Standard solenoid valves are supplied as single coil units. Doublecoil units are also avail-able for customers who require actuatorsto remain in last position during electrical power failure.
VALVE DESIGN Pilot Operated Spool
MEDIA Dry or lubricated air or inert gases
SPRING RETURN ACTUATORS The Series 63 Solenoid Valve fills thespring chamber with supply air rather than drawing air from thesurrounding atmos-phere. This keeps the spring chamber clean anddry, and improves the performance and service life of the actuator.

ELECTRICAL CHARACTERISTICS

IP65 DIN Housings: 24, 120, 240 Volts AC, 50-60 HZ 12, 24, 120Volts DC, 50-60 HZ
Insulation-Class F Coils Maximum Temperature Rating: 311°F (155°C)
FLOW - 1/4" PIPE: Cv = .7 Flow = 30 scfm, 150 psi max. Note: BrayS92/93 actuation times are very dependent on the flow capacity oftheir air supply. It is strongly recommended that only the Bray S63high flow solenoid be used with the Bray S92/93 actuators. The useof smaller port solenoids, solenoid man-ifolds, small I.D. airsupply tubing and/or extended lengths of tubing can significantlyreduce the actuation time and/or the initial response to thecommand signal.
