The GEMÜ 790 ball valve series has a compact yet robust design. At the same time, it is suitable for use up to a pressure rating of PN125.
The highly polished and precisely manufactured GEMÜ 790 series ball fits snugly and air-tightly into the internal seal contour. A discharge slit in the seal ensures pressure relief in the valve flow. This not only reduces the seat wear but also lowers the actuating torque required to rotate the ball. This enables both cost-effective and energy-efficient system operation. The additional pressure relief hole in the ball enables pressure compensation, preventing a potential failure due to an internal build-up of pressure. Blow-out protection in the shaft ensures maximum operational safety. The antistatic device provides a permanently conductive connection between the ball and the shaft. A tongue-and-groove-style connection between the shaft and the valve body enables full earthing of the ball valve during installation in the system. This also ensures that it is safe for use in ATEX areas.
The stainless steel ball valves of the GEMÜ 790 series are designed to enable quick and easy servicing of internal wearing parts at all times.
