There are two pressure control valves: one is a pressure relief valve, and the other is a pressure reducing valve. Pressure relief valves have higher flow capacities than pressure reducing valves because pressure relief valves have to be capable of directing all flow to the tank.
Pressure relief valves are used in hydraulic systems to limit the system pressure to a specific set level. If this set level is reached, the pressure relief valve responds and feeds the excess flow from the system back to the tank.
Note: the pressure relief valve is a normally closed pressure control valve.
A hydraulic system can only function - as per requirements - by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. Get advice and suggestions from DTA in order to select the appropriate hydraulic valve, in terms of size and function, that suits your application and your budget.
DTA has extensive expertise with hydraulic valves and carries a substantial inventory of hydraulic valves in different sizes, valve spool configurations and solenoid voltages. We only supply high-quality hydraulic valves, taking into account a wide variety of functional and hydraulic system requirements.
Hydraulic valves are available from several major vendors; our preferred hydraulic valve suppliers are Parker Hannifin and Denison Hydraulics. Additionally, we supply hydraulic valve parts and accessories such as sub plates, seal kits, O-rings, solenoids and hydraulic valve control electronics.
DTA is serving your industry with the supply of hydraulic parts and hydraulic components for more than 25 years. Since 2010 we have been fully qualified and certified as distributor hydraulics by Parker Hannifin. Together we developed a rapid delivery program for the genuine Denison Hydraulics single and multiple vane pumps. We support industrial and mobile applications and hold a considerable inventory of genuine parts, components and sub-assemblies.
