TYPE 2FRM 20
Flow control valves are 2-way flow control valves. They are used to maintain a flow constant independently of pressure and temperature. The valves basically consist of the housing, orifice bushing, pressure compensator with optional stroke limiter, check valve, adjustment element. The flow from channel A to channel B is throttle at the orifice. In order to maintain the flow across the orifice constant, a pressure compensator is connected upstream of the orifice. The flow is maintained largely independent of temperature due to the orifice design. Free return flow from channel B to channel A is directed via the check valve. The flow is only controlled from A to B. In order to control the flows in both directions a rectifier sandwich plate type Z4S can be installed below the flow control valve.
TYPE 2FRM 6
The flow control valve type 2 FRM is a 2-way flow control valve. It is used for maintaining a contant flow, independent of pressure and temperature.The valve basically comprises of housing, rotary knob, orifice, pressure compensator and an optional check valve.
TYPE AF 6
Pressure gauge isolator valves type AF 6 are 3-way longitudinal valves for manual operation. They serve to check the prevailing operating pressure from time to time.In the initial position, flow from P to the pressure gauge via the spool is blocked and the pressure gauge is connected with T. When the button is pushed, the spool is moved into the switched position, giving free flow from P to the pressure gauge and the connection to T is blocked. By rotating the push button, the spool can be locked in place via a detent. After operation, the spool is pushed back into the initial position by the reassure spring and thereby unloads the pressure gauge. The pressure gauge can be directly crewed into the valve housing or fitted separately.
TYPE DV - TYPE DVR
The throttle/isolating valves type DV serve to set an exact oil flow, and can be used for shut-off function, too. The throttle/check valves type DRV serve to set an exact oil flow in one direction, and to allow free return flow in the opposite direction. They consist basically of a housing, adjustment knob with locking device. By turning the adjustment knob to the left, the spindle with throttle pin increases the flow section to maximum. By turning the adjustment knob to the right, the spindle with throttle pin decreases the flow section until fully closed without leakage. For repeat setting, a color scale is provided on the top end of the spindle. The area of colored triangle showing indicates how far the valve is open (the larger the colored triangle the greater the opening). The flow setting is locked by means of locking device.
Check-Q-meters are used in hydraulic systems to influence the speeds of hydraulic motors and cylinders independent of the load (prevents running away). In addition there is an isolator function for pipe burst safety. The check-Q-meter comprises basically of the housing, main poppet, pilot part, pilot spool, damping spool and pilot damping.
TYPE HED 1
Hydro-electric pressure switches type HED 1 are piston pressure switches. Type HED 1 pressure switches have the task of switching on or off an electrical circuit dependent on pressure. The live electrical terminals are covered by an isolating strip. To adjust the switching pressure, the name plate must first be removed and the locking screw loosened. The switching pressure is set by rotating the adjustment screw. Finally, the adjustment screw must be secured by the locking screw and the name plate refitted.
TYPE HED 4
For subplate mounting. For pipe installation. 3 pressure stages. Plug-in connector with circuit (indicator lamp) (separate order).
TYPE MG - TYPE MK
Valve types MG and Mk are pressure and viscosity dependent throttle and throttle check valves.
Multi-circuit gauge isolators type MS 2 with built-in pressure gauge (6 meausing points). With this valve, the rotary knob has a glycerin damped pressure gauge fitted. By turning the rotary knob and the sleeve which is connected to it, until the indicator on the rotary knob points to one of the 6 measuring points, 1 measuring point is connected to the pressure gauge. In order to unload the pressure gauge there are zero points between each measuring point. In this way the pressure gauge is connected to the tank (connection T) via the drilling in sleeve and is thereby unloaded. A built-in detent holds each selected position. Which measuring point is connected to the pressure gauge, is indicated by the arrow which is situated on the rim of the rotary knob.
