GENERAL FEATURES: • The valve is manufactured in 316L stainless steel and suggested for particular hygienic conditions (food industry applications). • Valve with 4 ball seats. Inlet from any of the 3 ends. It can also shut of the flow. • Ends: as per DIN 11851 specifications. • Working temperature: from -20°C to +150°C • Working pressure: see table. • Fluid range: food industry. • ISO 5211 flange connection. • The manual version (with lever) doesn't have the ISO 5211 flange connection and its therefore not possible to mount on it any kind of actuators.
ON REQUEST: • Connection: SMS - MACON - DIN male. • Seals made of:
PTFE glass filled,
PTFE with carbon graphite,
High-molecular weight polyethylene.
• For other applications, please contact our sales department.
CERTIFICATIONS: • ATEX version in conformity with European Directive 2014/34/EU. • ATEX certificate on request.

Torque can vary depending on temperature and type of fluid; a safety factor of 1.4 must be applied. Torque can drop on high frequency of operations. The actuator/valve sizing, indicated on the following pages, are based for valves to be used with liquids or gaseous fluids, clean, and for medium temperatures. For further information, or different uses please contact our sales department.
Plan for "L" port
N.B.: “A” must be the rest position of the ball with SR FAIL CLOSE actuator. “B” must be the rest position of the ball with SR FAIL OPEN actuator.
View from above
Plan for "T" port
With actuator 2 positions with 90° rotation are possible only: the configuration of the ball must always be communicated at our sales department.
N.B.: Choose the rest position of the ball with SR FAIL CLOSE actuator; whenever supplied with air, actuator turns in an anticlockwise direction. Choose the rest position of the ball with SR FAIL OPEN actuator; whenever supplied with air, actuator turns in a clockwise direction.
