Slide valves

Slide valves SG are used to limit the flow of a powder/granular product (non toxic). The slide valve
has a perfect seal in the external body, while under the blade the perfect seal is guaranteed only for granule products.

Each slide valve is manufactured with a special seal arrangement which stops the product from entering the internal workings via the sliding plate. Slide valves are commonly utilised when full flow of the product is required or where the height for mounting the valve is minimal.

Sizes: square 150, 200, 250, 300, 350, 400, 500, 600, 700 and 800mm.
Also available with round inlet or rectangular.

Shaft: threaded spindle - smooth.

Material: carbon steel - stainless AISI 304 and AISI 316.

Mix slide valve

Seal: standard seal (not fully leaktight for fine powders)- improved blade seal.

Actuator: manual - pneumatic (Ø63mm, Ø80mm, Ø100mm, Ø125mm cylinder; 24VDC, 48VDC, 24VAC, 48VAC, 115VAC, 230VAC) - electric (0,37kW, 0,75 kW).
Available with position indicator and mechanical or inductive limit switches.

Pinch valves

The MIX pinch valve is easy to be installed and outperforms in controlling a wide range of products coming from pneumatic conveyance in pressure. It is made of a pair of identical long lasting anti-abrasive seals contained within two split bodies in aluminium. After an accurate research and planning, the design of the MIX pinch valve is able to guarantee the following advantages:

  • Reduced wear from abrasion of the seal, thanks to the largest central flow area;
  • Perfect closing achievable with less air pressure control, and therefore longer service life;
  • No maintenance required;
  • No mechanical wear.

Sizes: DN80 and DN100

Seal: pair of identical long lasting anti-abrasive seals contained within two split bodies in aluminium.

Actuator: electro-valve (24VDC, 48VDC, 24VAC, 48VAC, 115VAC, 230VAC).

Accessories: pressure switch - pressure reducer - compressed air reservoir - flanges - connecting kit between silo and truck - truck connection indicator.

Silo butterfly valves

Butterfly valves type SVQ-SVT with diameter ranges Ø250 and Ø300. These butterfly valves are commonly installed on the outlets of silos - hoppers – mechanical conveyors – airflow systems – etc. The valve body is made of carbon steel, with a special shape: thanks to the beading in the middle of the valve’s body, its structure is stronger, even though light.

The double round-flanged butterfly valve SVT is for installation in the flow of a product; while the SVQ version is supplied with a square-shaped upper flange and with a round-shaped bottom flange, suitable for rigid canalization. An optional spigot (SFU) can be supplied, if a flexible canalization is required

Monobloc seal. High seal profile that covers both the upper and bottom flange (Water-proof in the Silo-valve coupling, it doesn’t need other gaskets or adhesives products).

Beaded valve body (in order to leave space, during the closing operation, to the seal).

Friction-proof ferrule mounted in the drive and driven shafts (less physical effort for the User, during the valve’s closing/opening and a longer life-time for the valve).

SVQ version is provided with anchorage system by 4 anchorage brackets. Every fixing is guaranteed from a bolted connection completed with wedgeshaped washer (The bolts will not suffer a deformation and it will maintain a uniform distribution of the load).
