Butterfly valves, since their invention in 1960’s became one of the most demanded flow control elements in industrial and domestic flow control applications due to their light weight, low pressure loss, 100% leak free operation, easy and economic automation capabilities. Beside the soft seat applications, development of PTFE seats and metal seats of double eccentric high performance valves today,butterfly valves are used from basic water applications to industrial applications and highly corrosive severe service applications. Butterfly valves have wide range of applications in water, sea water, steel, food, paper, chemical, petrochemical and all HVAC and general industrial flow process controls.

Available in sizes from 1/4" to 4" with BSP threaded end connections. Face-to-face Dimensions are according to DIN3202-M3 and PN63 working pressure. Ideally suited to be used as a manual isolation valve in a wide range of process applications involving liquids, gases and steam.

Available in sizes ranging from DN50 to DN600 with either Wafer or Lug body configurations. Ideally suited to be used in lines containing fibrous particles and liquids with suspended solids. Main Application Areas are Pulp & Paper Industry, Wastewater Treatment Plants and Under Silo.  Bonneted versions are available for vacuum and pneumatic conveying systems

Ideally suited to be installed as a tight shut-off or control valve in lines particularly containing abrasive or corrosive chemicals,slurries,powders,gases and high viscosity liquids with suspended solids which tend to clog conventional valves.Face to Face dimensions are according to BS 5156(short-pattern) or DN3202-F1(long-pattern). Available as unlined or lined with flanged or threaded end connections.

Proval V961 Pressure reducing valves pressure reducing control valves are hydraulic control valves which give high inlet pressure to the desired low pressure value thanks to the pilot mounted on them.The valve keeps the desired output(low) pressure constant without being affected by the flow rate and inlet(high) pressure values. The valve automatically closes itself when there is no flow in the system.When the valve in the system drops below the pressure value, the valve opens itself. Pressure reducing valves can be used horizontally or vertically in the system. The outlet pressure setting of the valve is set at the factory as 2,5 bar. Proval V961 Pressure reducing valves are used in water distribution and filtration systems. Thanks to the design of the Proval V961 Pressure reducing valves, high corrosion resistance is achieved.

Available in sizes ranging from DN40 up to DN600.

Proval A210 Series innovative, compact design pneumatic rack and pinion rotary actuators including all critical components are manufactured in-house using dedicated state-of-the-art CNC machines following ISO quality assurance standards. Proval pneumatic actuators that can be set either to fail-open or fail-close, comes in 18 different sizes in both double and single acting types.  A210 Series of actuators having torque figures in ranges 9 to 9767 Nm are well suited to operate part-turn valves such as plug ,ball and butterfly valves.

A100 EP series electric actuators are manufactured for on/off or proportional control of quarter turn butterfly, ball and plug valves and dampers.

Proval hydraulic actuators are used in rotary valves especially in marine applications.

Proval A300 Series rotary hydraulic actuators are designed for use in rotary type butterfly and ball valves especially in marine & shipbuilding applications.
