Richter diaphragm valves, known for ease and reliability, are widely used for shut-off, control, and throttling due to their reasonable pricing.
PFA/PTFE lined valves are ideal for corrosive substances in chemical, pharmaceutical, food, and industrial processes. The valves ensure hermetic tightness, FDA compliance with wetted PFA and PTFE materials, soft-sealing, and gas-tight performance. They operate at pressures from -30 to +150 °C and are rated at PN 16 (up to DN 50 or 2˝) and PN 10 (DN 80 or 3˝ and larger) for various applications.
