VER03M
VERO 3M

PROPORTIONAL PRESSURE RELIEF VALVES 

Mounting Surface NFPA R03 (D03) (ISO 6264-03-04-*-97)

Max Pressure 5000 PSI (350 bar)

Max Flow Rate 1.32 gpm (5 l/min)

 

VER03M is a direct operated proportional relief valve, with mounting in compliance with NFPA/T3.5.1 R2-2002 and ISO 6264:1998 standards.  The VER03M valves are designed to modulate pressure in a hydraulic circuit directly proportional to the input current to the valve.  The valve consists of a poppet, seat, spring and proportional solenoid. The spring and solenoid force acts on the poppet holding the valve closed. When system pressure exceeds the spring and solenoid forces, the valve begins to open and modulate P port pressure by discharging excess flow to tank. System pressure can be changed by changing the current to the solenoid.  There are four pressure ranges available: 70 bar, 140 bar, 210 bar and 350 bar with flow up to 1.32 gpm.  Any back pressure in T port is added to the controlled pressure in P port. The maximum recommended T port pressure is 30 psi while the valve is controlling pressure.  The valve can be driven by a variable current power supply or an external power amplifier card designed to maximize the valve’s performance.

 

 


VER03MG
VERO 3MG

PROPORTIONAL PRESSURE RELIEF VALVES WITH ON-BOARD ELECTRONICS

Mounting Surface NFPA R03 (D03) (ISO 6264-03-04-*-97)

Max Pressure 5000 PSI (350 bar)

Max Flow Rate 1.32 gpm (5 l/min)

 

The VER03MG direct operated Proportional Relief Valve, with On-Board Digital Amplifier conforms to NFPA D03 / ISO 6264 standards.  VER03MG valves are designed to control maximum pressure in low flow systems or as the proportional pressure pilot valve of larger two-stage pressure control valves.  Output pressure is controlled proportional to the input command reference signal supplied to the On-Board Digital Amplifier.  Four pressure ranges are available to help match your requirements.  The On-Board microprocessor controls all the valve functions and is preset to optimal valve performance. In field adjustments can be performed, via software, to customize the parameters based on your application needs.

 

 

VER03MP
VERO 3MP

PROPORTIONAL PRESSURE RELIEF VALVES PILOT OPERATED

Mounting Surface NFPA R03 / D03 (ISO 6264-03-04-*-97)

Max Pressure 5000 PSI (350 bar)

Max Flow Rate 13.2 gpm (50 l/min)

 

Continental Hydraulics VER03MP pilot operated proportional relief valves conform to NFPA R03/D03 and ISO 6264:1998 mounting standards.  The VER03MP valves are designed to modulate pressure in a hydraulic circuit directly proportional to the input current to the valve. The valve consists of a proportional pilot relief stage and a main relief stage. The main stage has a spool which is held closed by a spring. System pressure acts on the opposite end of the spool opposing the spring force. When system pressure exceeds the spring force, the valve begins to open. The spring preload sets the minimum controlled pressure. System pressure can be increased from minimum by increasing the pilot pressure which adds to the spring force. The spool will tend to close until the system pressure reaches its new setting.  There are four pressure ranges available: 70 bar, 140 bar, 210 bar and 350 bar with flow up to 13.2 gpm.  It is an internally piloted valve with three drain options - internal through T port, external through A port and external through Y port.  The valve can be driven by a variable current power supply or an external power amplifier card designed to maximize the valve’s performance.

VEP03MSV
VEP 03 MSV

3 WAY MODULAR PROPORTIONAL PRESSURE REDUCING / RELIEVING VALVES

Mounting Surface NFPA D03 (ISO 4401-03-02-0-05)

Max Pressure 4600 PSI (320 bar)

Max Flow Rate 13.2 gpm (50 l/min)

 

The VEP03MSV-PDRP is a D03 modular three-way proportional pressure reducing/relieving valve which conforms to NFPA D03 and ISO 4401 mounting standards.  These valves are designed to provide remote variable pressure control in the pressure port of a secondary circuit. The controlled pressure is proportional to the amount of current supplied to the solenoid.  As flow demands change, the valve opening will modulate to maintain the circuit pressure. The VEP03MSV-PDRP will also relieve the tank to vent a load induced pressure spike. In event of a loss in electrical power, the valve spool will return to the low pressure condition.  The proportional solenoids can be driven by a variable current power supply or by use of external Power Amplifier Cards designed to maximize the valve’s performance.
