Siral Valves
Control Systems & Sensors
Siral develops valves and actuators for HVAC and light industrial applications. Its portfolio includes water and low-pressure steam control valves, with compact zone valves for terminal equipment. Modular 6-way valves allow a single coil to provide heating and cooling, while butterfly valves address larger flow requirements. Compatible actuator options support different control strategies. Product selection reflects the system’s operating conditions and piping arrangement, helping project teams match flow control to equipment requirements and available installation space.
The Experience Behind Every Recommendation
Behind every equipment solution is Havtech’s own established legacy of commercial HVAC expertise, driven by our decades of experience, extensive project history, and trusted industry relationships.
Product Categories
Products That Fit Your Needs
Siral’s valves and actuators deliver precise flow control and flexible installation options, supporting efficient HVAC operation across commercial and light industrial applications.
Water Control Valves
Water control valves regulate flow through heating and cooling coils. Two-way and three-way configurations support applications ranging from fan coils to air handlers, with characterized flow control designed for accurate coil regulation.
Zone Valves
Compact zone valves support flow control in fan coil units and radiant panels. Field-adjustable flow settings help match equipment requirements, with compatible actuators offering on/off or modulating operation to suit the application.
Modular 6-Way Valves
Modular 6-way valves control heating and cooling through a single coil using one actuator. Different flow capacities for each operating mode accommodate system requirements, supporting applications such as chilled beams and fan coil units.
Steam Control Valves
Designed for low-pressure steam, these compact control valves suit equipment with limited installation space. Applications include fan coil units and unit ventilators, with valve construction developed specifically for steam service.
Butterfly Valves
Butterfly valves provide high-volume flow control for cooling tower isolation and chiller bypass applications. Two-way and three-way configurations are available, with electric or pneumatic actuators to suit the system’s operating requirements.
