The GRAT Electric CPVC Plastic Butterfly Valve is the preferred solution. Its lightweight, corrosion‑resistant construction handles salt‑rich corrosive media, delivers reliable on‑off shut‑off and precise flow modulation, and fundamentally eliminates fluid‑leakage risks.
The GRAT Electric Tank‑Bottom Ball Valve with weld‑plus‑flange construction delivers reliable tank‑bottom emptying for powders, granules and slurries, resolving buildup, jamming, leakage and automated‑discharge challenges.
GRAT 600S Low‑Load Electric Butterfly Valve solves sticking and ash jamming for high‑temperature dust‑laden ducts up to 450 °C. Its link‑free lightweight design ensures reliable air‑volume regulation and lower O&M expenditure.
For skid‑mounted purification units adopting amine‑based acid removal (desulfurization / decarbonization) in natural gas and coal‑chemical processes, the GRAT Pneumatic Single‑Seat Control Valve is the preferred option. It is suitable for MDEA amine liquid circulation, acid gas service and high‑temperature heat‑exchange conditions, and addresses key pain points of conventional valves including corrosion‑induced sticking, poor modulating performance, high amine‑solution loss and off‑spec purification output.
