Cast steel gate valves

Cast steel gate valves

Product catalog summary

Body Specifications
The gate valve body is made from cast steel, designed with a high safety factor, and exceeds API and DIN standards in thickness. Series 150 features an oval central body section, while Series 300 transitions from oval to circular, and higher series maintain circular sections for stress distribution. Diameters comply with ASA B.16.5 standards, and flange thicknesses exceed minimum requirements. The body includes cast sliding guides to prevent incorrect assembly, with precision machining on CNC machines.

Cover Specifications
For external screw models, the cover can be integral or separate, depending on diameter and series, with thickness matching the body. A threaded housing for the "Stem seat" allows seal maintenance during operation, and a deep stuffing box chamber is included for stem seal arrangement, adhering to API and DIN specifications.

Material and Treatment
Bodies are typically cast in ASTM-A 216-WCB carbon steel, with options for other steel alloys, stainless steel, or antifreezing steel. All castings undergo thermal treatment and sandblasting.

Technical Characteristics
Gate valves are suitable for water or low corrosive substances, with operating temperatures from -35°C to +427°C. Pressure-temperature ratings range from ANSI 150 to 600 Lbs, adhering to ASME B16.34, API 598, API 600, and API 6D standards.

Dimensions and Weights
Specifications for Class 150, 300, and 600 valves include face-to-face lengths, center heights, hand wheel diameters, and weights, varying by nominal diameter and class.

Materials Comparison
The document compares materials for bolts and nuts, detailing ASTM and DIN standards.

Production Range
The range includes various valve types such as gate, check, butterfly, disc, needle, spindle, Venturi, hydrant, delivery regulating, pressure regulating valves, and more, adhering to DIN and ANSI API standards.

Check Valves
Specifications for non-return check valves and swing check valves range from ND 2” to ND 24” in Class 600.

Ball Valves
Available in Class 150 and Class 400 for sizes ND 4” to ND 20”, and in Class 300 and Class 600 for sizes ND 1 1/2” to ND 20”.

Penstocks and Gates
Includes cast iron penstocks up to ND 3000 x 3500, with custom sizes available on request. Stainless steel and steel gates are also available on request.

Trashracks and Filters
Various types of trashracks and filters, including fixed, extractible, drum, cleaning, and mechanical types, are available with sizes on request.

Joints
Steel and stainless steel dismantling and expansion joints are offered.

Automatic Radial Gates
Available in both steel and stainless steel.

Special Applications
Includes solar-powered distribution systems and motorized valves, pressure and flow regulating valves, discharge valves, and emergency valves.

Il corpo è di acciaio fuso ed è ampiamente dimensionato così da deter minare un alto fattore di sicurezza. Gli spessori sono sempr e superiori ai minimi stabiliti dalle norme API e DIN std. Particolare cura è stata riposta nella progettazione della Serie 150 dove la sezione ovale del corpo centrale si presta a deformazioni disuniformi. La Serie 300 ha anch’essa il corpo centrale a sezione ovale, ma limitatamente alla zona dei seggi, che va però allargandosi ﬁno ad assumere la sezione circolare. I corpi delle serie superiori hanno tutte la sezione circolare onde consentire una distribuzione delle...
