The Brand, Series 83 is a two port, non-adjustable, pressure compensated, inline flow control, with free reverse flow. The amount of flow is determined by the diameter of the orifice in the compensator piston. The spring and piston are held in place when it is connected to an #8 SAE male fitting. This flow control is inexpensive and gives the customer the ability to change the flow rate by swapping the piston with another that has a different size orifice.

The VFL volume flow limiter simply deals with what is normally the tedious and xpensive process of adjusting flow rates in ventilation and air conditioning systems. Easy installation and precise operation saves precious time on site. The required volume flow rate can be simply set up at the point of installation when the VFL is fitted into the duct work.
The VFL controls to the set volume flow rate keeping it constant within strict tolerances even when the upstream pressure changes.

These valves control the reciprocating and rotating speed of hydraulic actuators, A variety of flow control valves including pressure and'or temperature-compensated Mow control valves is available.
Flow Control Valves/Flow Control and Check Valves
These valves are pressure and temperature compensating type valves and maintain a constant flow rate independent of change in system pressure (load) and temperature (viscosity of the fluid). They control the speed of the actuator precisely. The valves with an integral check valve allow a controlled flow and reverse free flow. Repeated resetting can be made easily with a digital readout.

Various type of pressure control valves are available, from relief valves to pressure switches, to control the pressure at suitable level in the hydraulic system.
Low Noise Type Pilot Operated Reliel Valves
Pilot operated relief valves here have been particularly developed as low noise type. To protect the pumps and control valves from an excessive pressure, the valves are used to control the pressure in the hydraulic system to constant level. The remote control and unloading can be done by using the vent circuit.
