Pressure Reducing Valve (for Air and Gas), GD-43-10 / GD-43-20 Series

Pressure Reducing Valve (for Air and Gas), GD-43-10 / GD-43-20 Series

Saves on space and resources. Stainless steel is used for parts contacting liquid, Teflon is used for fluid-contacting surfaces, and a special fluorine rubber is used for rubber parts to provide superior corrosion resistance and durability.

Saves space and resources (makes separation and collection for resource recycling easy because materials are visible through the valve box and the lower cap).
· Stainless steel materials (SCS14A and SUS316) are used in liquid-contacting parts, increasing corrosion resistance.
· Teflon is affixed to the liquid-contacting surface of the diaphragm, preventing deterioration due to liquids and providing superior corrosion resistance.
· A special fluorine rubber with superior corrosion resistance is used.
· A pressure-balancing valve structure ensures that the pressure on the secondary side is always kept constant without being affected by temporary side pressures.
· The GD-41 and 43 models feature sealed structures which do not allow external outflows even when the diaphragm is damaged.
· Safe fluorine grease is used on the O-ring.
· Can also withstand the above for cleaning and sterilization for the purpose of cleaning and sterilizing the system and the inside of piping.
· Pipes can be installed either horizontally or vertically.
