Drain Valve for QS Filtration

The drain valve for QS series filter tanks is a shut-off fitting located in the lower part of the tank, which enables draining the water from the filter tank before winter conservation, replacement of the filter media or servicing work. Correct draining of the filter tank before winter is crucial for preventing frost damage – the residual volume of water expands when freezing and causes the tank to crack. The valve is easily operated by turning or pulling out the closure. The tightness of the valve during operation prevents the leakage of pressurized water. The original part is precisely compatible with QS tanks and guarantees correct function.
