Soft seated ball valves

The maximum operating temperature of soft seated ball valves is usually +250˚C.

In the case of valves by ALFA Valvole, the Fire Safe EN ISO 10497–API607 V test requirements are followed.

Antistatic properties conform to the norm BS 5146 and TA-Luft TÜV.

Small size classes are most often with a floating structure and large size classes with a supported ball structure (trunnion). Nevertheless, in some circumstances, for example, high flow rates, trunnion should be preferred in smaller size classes as well.

In addition to 2-way valves, we also supply 3-way valves. Several sealing alternatives are available, e.g., PTFE, RTFE, TGV, AM, DEVLON, etc.

In the case of 90° rotating 3-way valves, we have models with a L and a T ball in the range. In the case of the L ball, this is supplemented by a full-bore transflow in the case of 120° rotating valves and a sluggish medium.

Our range includes valves by manufacturers such as ALFA Valvole, FEMA Srl OMB Spa
