Snubber is intended to suppress the effect of sudden pressure pulses and fluctuation of pressure peaks. It is provided with adjustable screw to restrict the flow as per operating condition. Pigtail Type & āUā shaped siphon are intended to protect pressure gauge from the effect of hot pressure media such as steam and also to reduce the effect of rapid pressure surge. The steam condensate inside the coil of siphon prevent direct contact. Needle valve is intended to isolate the pressure gauge from pressure medium or to throttle and to damp pressure pulses.
