Ritec partnerDyna-Flo 370 series large sliding stem control valve
12" sliding stem control valve with 12", 14" or 16" flanges, ASME Class 150 to 600, cage guided, shutoff Class IV to V, for large flow gas, steam and liquid control.
The 370 series is Dyna-Flo’s large sliding stem valve: a 12” body that can be flanged 12”, 14” or 16” to match the line. It keeps the cage-guided globe design, with balanced plugs to limit the actuator size, and is used where a rotary valve does not give the required rangeability or shutoff.
It is supplied with DFLP piston actuators and available in ASME Class 150 to 600.
Selection data we need
Medium and its properties, inlet and outlet pressure, flow rate at minimum, normal and maximum conditions, temperature, allowable noise level, required shutoff class, pipe size and rating, actuator air supply and control signal, and any fail position. We size the valve and actuator in Dyna-Flo’s FloSpec software.
Applications
- Large steam and gas headers
- Turbine bypass
- Cooling water and large liquid lines
