Features:

• Isolation valve approved for drinking water
• Anti-Clockwise (FAH) or Clockwise (FSH) closing
• Complete and direct passage
• Reduced operating torque
• Reduced operating torque stainless steel handle with thread obtained by the cold rolling process, which allows maintaining the steel structure and increasing its mechanical strength

• Allows the replacement of the spindle sealing O-rings with valve under load
• Fully vulcanized cover in EPDM approved for drinking water (ACS)
• Top of the wedge designed with a “soft stop” system, which acts as an end stop, for the valve fully open
• Brass key nut, firmly anchored in the key, avoiding vibrations and ensuring greater longevity
• Valve body and key designed with a “monorail” system
• Fully EPDM body/cover seal housed in a cavity designed to couple it, surrounding the screws, ensuring a perfect seal
• Integrated and sealed A2 stainless steel body/cover screws, ensuring total protection against corrosion
