The changeover valveCV-1500Series permits to intercept one of two valves mounted on it making operate simultaneously the other one and permitting to carrying out the disassembling and the maintenance of the intercepted valve. The simultaneous interception of the two valves is never possible.

TECHNICALoffers a particular type of control valve to the Oil & Gas industry: the liquid discharge valve GV Series 20000 .

The pneumatic pressure switchPP 10000Series, designed and produced byTechnical srl,can be efficaciously employed in automating a line in pressure or a plant. The pressure switch controls a pneumatic signal either in case of dropping or in case of increasing of the line pressure on which it is installed. The line pressure is detected by a piston opposite to an adjustable spring through a spindle. When the pressure reaches the setting, the distributor block the signal pressure and joints the outlet to the vent line. The PP 10000 pressure switch can operate also in the reverse mode: the signal pressure is put on when the set pressure is reached. The setting pressure can be done on all the range of the spring either in the “high pressure” or in the “low pressure” working.

The REF 3000 Series velocity check valve is used to automatically block the flow of the line on which it is installed in the case of an increase in speed due to the opening of the circuit downstream because of a maneuver, the collapse of a fuse plug, the breakdown of a seal or any other event which causes the downstream fluid flow.

The universal SV3 Series pneumatic servovalve make it possible to automate a line under pressure. This is achieved by employing either a pneumatic signal or manual action to activate the Three-way distributor which switches over the internal connections. The following configurations are available: automatic, with manual reset, bistable and manual.
