Primarily designed to function as a non-return valve, but has the capacity to hold the valve closed. The 803 combines all the features of both the 801 and the 802 valves into one unit, making it ideal for situations where it is not practical to install two valves or where safety is paramount.
• Sizes and pressures ranges are equivalent to that of the 801.
