Kromschroeder 03152149 manual cock for DH15R50

Kromschroder DH15R50 push-button cock for manometer, 03152149 — a compact shut-off valve with spring return (manual cock), designed for impulse connection of a manometer to a gas or air line. It allows control pressure measurements without constant load on the measuring device and without stopping the process. If you need to periodically check gas pressure in the system but do not want to keep the manometer under constant pressure (to extend its service life) or you do not have a stationary manometer, this cock is the optimal solution. Technical specifications Parameter Value Part numbers 03152149, 624.439.046 Model DH 15R50 Manufacturer Kromschroder (Germany) Type of cock Manual, push-button (manual cock), with spring return Connection type Internal thread Rp ½" (DN 15) Max. inlet pressure 5 bar Purpose For protecting manometer from water hammer and pressure, air, gas Working medium Natural gas, liquefied gas, air Medium temperature from -20°C to +60°C Weight 0.256 kg Price (approx.) ~10,000 ₽ ✅ How it works and why it is needed The operating principle of this cock is extremely simple but very effective for maintenance. In normal state, the cock is closed: the manometer is isolated from the measured medium and experiences no load, which prevents wear of its internal mechanisms and the influence of pressure pulsations. The measurement process is as follows: Connect the manometer to the outlet nipple of the cock. Press and hold the button — the cock opens, pressure is applied to the manometer, and you see the current readings. Release the button — the cock automatically closes under spring action, the manometer is disconnected and remains without pressure. ✅ Key advantages Safe and periodic diagnostics: Ideal for connecting a portable manometer during commissioning work or
