Top Butterfly Valve Manufacturer in Italy
Butterfly valves regulate the flow of media and are part of the quarter-turn family of valves. This means that with a 90-degree turn of the handle or actuator, you can either open or close the valve. This valve is characterized by a metal disc that is positioned perpendicular to the flow of media.
Butterfly valves are useful when space for larger quarter-turn valves is not available and the media requires a high coefficient of flow. However, slurries are not suitable for butterfly valves as these can damage the elastomeric seats easily.
Klinger was founded more than a century ago on the outskirts of Vienna. The company is widely known for innovative industrial products such as the level gauge for boilers, the soft-sealing piston valve, otherwise known as the Klinger valve, and the Ballostar, a type of ball valve.
The Klinger butterfly valve has soft and metallic sealing. It boasts of zero leakage rate and a wide range of construction materials, temperature, and pressure ranges. Klinger carries the Westad butterfly valves. These are designed to be used for LNG, LPG, and other critical applications.
The valve body ranges from DN 80 to DN 1000. Depending on the design, these valves can have the double eccentric or triple eccentric orientation in lug, wafer or flanged end connections. The Westad Scorpio 2X has a PTFE sealing material but the Scorpio 3x has the metal sealing element.
On the other hand, the Westad Cryoseal 2x is made especially for the LNG sector. It comes with a PTFE seal but this valve is also available in copper sealing. The bonnet is bolted and extended. The valves are suitable for extreme temperatures up to -196°C.
Top Gate Valve Manufacturer in Italy
Gate valves are shutoff valves that are used in either a fully open or fully closed position. The valve main components comprise of the valve body, seat, stem gland, disc, and the wheel. The combination of the seat and the gate movement shuts off or opens the valve. In the closed position, the gate disc is perpendicular to the flow of fluid. Gate valves have little flow resistance when fully opened. Gate valves are more suitable for gas and liquid in non-throttling services.
Parker is a global industrial name synonymous with industrial valves. The company offers a wide variety of solenoid valves. The maximum operating pressure can range from -0.9 to 275 bar, with a maximum flow rate of 650 liters per minute – 45 gallons per minute, depending on the design. The control method can be a hydraulic pilot or electrohydraulic.
The VSO LowPro solenoid valve is a small proportional valve designed to 57 SLPM with only 16 mm bt 14 mm in height. On the other hand, the Viking Xtreme is a valve suited for extreme pressure. The valve operating temperature ranges from -40 degrees Celsius to 60 degrees Celsius with a pressure range from 16 bar. The ports range from ⅛ to ½ inches.
Top Solenoid Valve Manufacturer in Italy
Solenoid valves are used when fluid flow should be controlled automatically. These valves have control units that are electromagnetically energized to allow or prohibit the flow of media. To move the valve in the open position, an electromagnetic field pulls the plunger. This plunger acts against the spring. To close the valve, the plunger moves to its original position via the spring.
Firsa is known for its cast steel valves and strainers. These valves are often used in chemical and petrochemical applications. Firsa has several certificates to boast including ISO 9001:2015, CE-1370-PED-H-FIR 001-19-ITA-rev-A, API 6D-1454, API 600-0202, ATEX-ITA-06-012, and FPAL-MI440132-2020.05.
Firsa gate valves can withstand pressure from 150lbs to 2500 lbs. These valves can have bolted bonnes, and O.S. & Y designs. The flanges have sizes ranging from 2 inches to 26 inches. Firsa gate valves are available in super austenitic, Duplex, and Super Duplex steels, nickel-based alloys, titanium, and molybdenum-6 materials. The valve sizes can range from 2 inches to 36 inches, depending on the design.
Top Ball Valve Manufacturer in Italy
Ball valves have a ball-like disc inside the valve that acts as the primary barrier that either allows or stops the flow of liquid or gas. This ball disc has an opening, often called a bore or port. This port can have the same size or smaller than the diameter of the pipe.
Ball valves are the ball of choice for applications that need to have reliable and air-tight sealing. That being said, ball valves are suitable for chemicals and gases as these need fast and secure shutoff.
GWC Italia is the parent company of GWC Worldwide Companies. For more than 40 years, GWC has been manufacturing different kinds of industrial valves for many general and severe applications. These include oil & gas, petrochemical, mining, power, marine, and other industrial markets.
Its trunnion-mounted ball valves can have the bolted body, welded body, top entry, cryogenic, two balls with one body DBBV and cast body designs. These valves can have size ranges from 2 inches to 64 inches with pressure class rating ranges of ASME 150 to 1500. These can have 1-3 piece body configurations with either a reduced or full bore design, depending on the design. The features include an anti-blow out stem and anti-static device with spring-loaded seats.
GWC flanged floating ball valves are constructed according to API and ASME standards. Its valve sizes range from ½ inch to 10 inches. These valves have pressure ratings that range from ASME 150 to ASME 600. These can come as a unibody with a reduced bore or a split body with full or reduced bore designs.
Top Control Valve Manufacturer in Italy
Control valves regulate the flow of media by opening and closing as well as controlling the amount that passes through the valve. Control valves are part of the control loop that directs a process. With that in mind, control valves receive instructions from a controller, often far from the control loop itself. Control valves often have two basic designs. The plug-and-seat design has a plug that moves against the seat to close the valve. The ball type, on the other hand, has a ball that turns against the seat for a closed position.
Valvotubi has more than 40 years of the valve manufacturing experience. It has acquired the ISO 9001: 2015, the ARPA (DM06 / 04/04 n. 174) “Test and Conformity Report” and the WRAS Certificates.
Valvotubi has five types of control valves under its control valves product line. The automatic float control valve, the pressure reducing valve, the flow control valve, and the pressure discharge/sustain valve. These valves have brass ball disc with 2Cr13 seating and a body made of ductile iron. The valve size dimensions can range from DN 50 to DN 600.
