Overview
A pneumatic diaphragm operated 3/2 way globe-type control valve built for high-temperature service up to 450°C across steam, gas, water and air applications. Its three-port configuration supports diverting and mixing duty, while metal-to-metal seating and an in-line repairable body ensure tight shutoff and easy maintenance in demanding process conditions. Supplied, sized and serviced for process plants across Nepal.
Features & Benefits
- Three-port 3/2 way design supports both mixing and diverting flow in a single valve.
- Rated for high-temperature media up to 450°C without loss of sealing performance.
- Metal-to-metal seating provides Class IV tight shutoff under thermal cycling.
- Diaphragm actuator delivers precise, repeatable modulation with high flow capacity.
- In-line repairable construction minimizes downtime during servicing.
- Direct or reverse acting actuator enables fail-safe selection to match process safety.
