Bellator Engineers manufactures a comprehensive range of Stack Damper Valves (SDV) in sizes from 300mm to 4000 mm in round shape and Square/Rectangular Shape and Pressure rating up to PN 1. Different Sealing materials for 99.95 % leak tightness are offered as per application requirement. Our Stack Damper valves are designed to abate heat loss from boiler and to thwart the ingress of rain water and our Stack damper valves are Suitable for Design temperature from -25 Deg. C to 825 Deg. C. Our Damper Valves can be offered with the Anti-blowout, drain lines, Seismic Qualified Design based on the application requirement. Our Selection Criteria of actuators for automation is mainly based on the Torque values derived from the dynamic conditions of process parameters to ensure the genuine selection and flawless operation of damper valves.
