Water traps, Sealing rings to EN 837-1

■Overview ■Overview

Water traps protect pressure gages and shut-off fittings from heating up (e.g. by steam) by the water column produced by the water trap.

2The max. working temperature is 120 °C at 160 bar, 300 °C at 80 bar or 400 °C at 63 bar. If the temperature of the measured medium is higher, a sufficiently long line has to be connected up- stream of the trap to enable heat dissipation.

■Design

The water traps are available in U shape (type B) or circular

shape (type D) to DIN 16282. They have a weld-on end

Ø 20 mm ⋅ 2.6 mm on the measurement side. The connection on the device side is a clamping sleeve G½ to DIN 16283.

The sealing rings to EN 837-1 are required to seal measuring in- struments for pressure with the process connection G½B.

The water traps are made of steel (P250GH) or stainless steel	Sealing ring 7MF9007-7A. to EN 837-1, dimensions in mm
(X 6 CrNiMoTi 17 12 2)

Water traps are designed as standard for max. operating tem- perature 120 °C at max. operating pressure 160 bar (300 °C at 80 bar, 400 °C at 63 bar). Water traps for higher operating pres- sures and temperatures are available on request.
