BONETTI ball valves series RSS (hand operated) and RSSA (actuated and automated)  have been designed specifically  for boiler Blowdown.

The ball shape and seating system described above are worldwide patented by Bonetti.

Features

• the seats are manufactured from a 'unique' material combining metal and special graphite layers that enables the valve to withstand high pressures and temperatures.
• the sealing system has been specifically designed so that the seat that chokes the process fluid during opening and closing sequences is not the same that grants in-line seal tightness and its sealing surface thereby protected from erosion and 'wire drawing'.

Extensive tests carried out in our test shop under the hardest conditions, combined with the feedback from the applications on a large number of plants, proved that series RSS/RSSA valves are most efficient and cost effective 'Blowdown Valves'.

• Manually operated type RSS.
• Pneumatically actuated type RSSA air opens - spring closes - with solenoid valve
• Electronically actuated type TDA 100, specifically designed for RSSA Valve. Full Automatic, equipped with electronic control device, easily programmable, to meet required operating times and procedures, the TDA 100 is designed to integrate and/or control Blowdown process.

 For very severe operating conditions and very high Δp,  BONETTI BLB for continuous blow-down  or BONETTI PBR for discontinuous blow-down/blow-off are proper and most suitable solution.
