Quality and Certifications

Our Products

Our equipments are engineered nearly exclusively in our office. Each part is designed for its specific use, according to Customer requirements and project specifications. On the base of these informations, we select the suitable solutions, according to high quality and safety standards. Generally our products are made of welded carbon steel with parts in stainless steel.For specific requirements (e.g. seawater) we use different materials (e.g. Duplex or Superduplex steel) and apply particular corrosion protections, for example by mean of rubber or ebonite coating, more efficient than the common epoxy and poliuretanic paint.The manufacturing is made in our workshops in San Stino di Livenza (Venice - Italy) and the Customer can follow each step of the production, starting from the raw material receipt, till the final inspection and the shipment.

Butterfly Valve

Plunger Flow Control Valve

Safety/Overspeed Butterfly Valve with Lever and Counterweight

The Butterfly Valve, usually double-flanged, is adopted to intercept the fluid in pipelines with medium and big diameter, both for open/close or flow adjustment operations.

The double-flanged butterfly valve, unless otherwise requested, is designed with double excentricity to make esier the perfect closing. The operation can be done manually with a gearbox provided with handwheel or can be done with an electic or pneumatic servo system.

The plunger flow control valve - also known as needle valve - is adopted for the adjustment of the water flow inside the pipeline. The flow control is made by the axial movement of the plunger, which has a calculated shape to reduce at the minimum the pressure loss and the vibrations in the pipeline.The movement of this valve can be done manually (by mean of a gearbox with handwheel) or with an electic actuator (which can be On-Off or continuos) or with an hydraulic cylinder which can open/close or just open (in this case a counterweight will close).

The safety/overspeed butterfly valve is usually adopted in the hydroelectric power plants, to protect the turbine.

The valve is kept normally open with the hydraulic cylinder under pressure; only in case of emergency (for example in case of too high fluid speed) the pressure of the hydraulic system will be reduced, so that the valve will be closed quickly, by means of its counterweight.

In this situation, the hydraulic cylinder has a braking function during the valve closing and then it gives the necessary force to open again the valve, when the pressure of the system will be again increased by hydraulic oil unit.

Our Main Products

Fixed Cone Valve

Dismantling Joints and Expansion Joints

Air-Release Valve

This type of drain valve, also named Howell-Bunger, is usually adopted for the bottom drainage of the dams, so that the power given by the hydraulic pressure can be dissipated.In most cases, to protect the area around the drainage, the valve is equipped with a steel cone, which contains the water flow.

The dismantling joint is usually installed in the pipeline to allow - thanks to its telescopic movement - the assembly and disassembly of the other hydraulic equipments.The expansion joint has the additional purpose to compensate the elongation of the pipeline, usually due to the filling and emptying with fluid or due to the temperature changes at which the pipeline is working.

The air-release valve has the purpose to optimize the water flow inside the pipeline, because it prevents the presence of air and therefore reduces the turbulence which could damage the other hydraulic devices and the pipeline itself.This valve can even have a triple function: get out the air during normal operation, let in a big air flow when the pipeline is filling-out and let out a big air flow when the pipeline is filling-in.
