Our Manufacturing Partner
Dofun Refrigeration Valves in Myanmar from Hnin Pwint Kyaw
ShanDong DoFun Refrigeration Technology Co., Ltd. manufactures high-precision cast steel refrigeration valves for industrial ammonia and CO₂ systems — stop valves, regulating and expansion valves, check valves and filter strainers.
Hnin Pwint Kyaw holds the exclusive import authorisation for Myanmar. Every valve we supply comes straight from the manufacturer with full certification, so factories and contractors receive genuine Dofun parts with manufacturer backing and technical support — not copies or grey-market stock.
Built for low-temperature systems
Cast steel bodies rated from -46°C to +150°C, purpose-designed for R717 ammonia and R744 CO₂ refrigeration circuits.
PS 60 bar working pressure
Pressure ratings suited to the high working pressures of industrial ammonia plants, with accurate flow control across the range.
CE 0036 certified, fully traceable
Supplied with CE 0036 approval documentation and model-level traceability, backed by our own quality guarantee and after-sales service.
