MADDALENA S58 GATE VALVE

MADDALENA S58 GATE VALVE

S58 gate valve. Flanged, union or spherical coupling versions. It combines the characteristics of a gate valve with that of a regulation valve. Suitable for use in irrigation, fire-fighting or water treatment systems. Combines low pressure drop, low flow resistance, gradual opening and closing, and good seal with abrasive liquids, hard waters or liquids with suspended particles.

GATE VALVE S58

Control gate valve combining the functions of a gate valve and a control valve. Combines low pressure loss, low flow resistance, gradual throttling, and good seal with abrasive liquids, hard waters or liquids with suspended particles. Extremely low pressure drop, very gradual opening and closing of the flow port, resulting in a minimal flow rate coefficient differential (kv) for each turn of the handwheel. Low and easy maintenance.

DESCRIPTION

The S58 is an elastic seal control gate valve. It consists of body, handwheel and gate. The body is made of ductile cast iron and is protected, both internally and externally, with an epoxy coating.The inlet is flanged PN 16; the outlet is available in flange-flange or flange-bayonet version with internal thread of 3” (DN 80) or 4” (DN 100) for the pipe section.

The passageway is completely unobstructed. The gradual closing and opening prevent water hammer. The handwheel can be padlocked in closed, partially open, or fully open positions (padlock not included in the scope of supply). The parallel face brass gate ensures hydraulic seal. It is securely attached to the handwheel to ensure gradual closing and opening, without vibrations or knocking. It rests on a self-expanding, wear-resistant elastomer ring. It is not subject to permanent deformation or seizing.

APPLICATIONS

The S58 gate valve is particularly suitable for use in irrigation, fire-fighting or water treatment systems, in mains water supply systems and for industrial applications.

COMPLIANCE

The S58 gate meets the Technical recommendations for the design and construction of remote operation systems in irrigation systems drawn up by ITAL-ICID and the Lazio Region.
