Armstrong's 401-SH/501-SH series inverted bucket superheated steam traps are specially designed to overcome multiple adverse factors such as overheating, high pressure, and small load.
In order to make the steam trap can work normally under harsh conditions, Armstrong invented a * inverted bucket trap with a sump. The sump holds enough condensate to maintain the seal throughout the discharge cycle. The small cup in the sump can float up and down the inlet pipe. As the condensate rises, it seals the steam intake pipe.
The condensate flows into the valve. Since the sump collects the condensate and allows the steam to flow in from the lower part of the inverted bucket, the discharge valve is tightly closed during the water collection period and there is no drip. In addition, the steam trap retains all the characteristics of the inverted bucket type steam trap:
Resistance to wear, corrosion, and water knock;
The lever mechanism will fully amplify the force provided by the barrel, and can open the valve under system pressure;
The valve hole is located at the top of the valve, and the dirt will not accumulate on the valve hole; Under the action of differential pressure washing, dirty small particles are discharged from the valve in a suspended state;
The discharge hole is protected by a water seal to prevent fresh steam from leaking. Small holes in the barrel provide automatic exhaust air;
Inverted bucket trap does not need special adjustment, condensate will not accumulate to cause water surge.
Inverted bucket steam trap is the use of condensate and steam density difference working principle, the internal structure is connected by the lever system inverted bucket, to overcome the steam pressure switch inverted bucket trap inside is an inverted bucket for liquid level sensitive parts, inverted bucket opening down.
Exhaust air performance
Good
Back pressure characteristics
Works well at high back pressure

Not afraid of water strike, long life
1. All moving parts in the inner cavity are stainless steel, resistant to wear and corrosion.
2. Because steam can not reach the valve seat hole sealed by water, there is no steam loss, high efficiency and energy saving.
3. Upside down floating barrel, will not be damaged and flattened, not afraid of water strike, long life.
4. The top of the inverted bucket is equipped with a vent hole. Continuous air discharge performance is good, will not form cold lag and gas blocking.
5. It is not affected by back pressure and can work well under high back pressure.
6. Reliable work, only two moving parts (lever - and inverted bucket), so there will be no jamming.
7. The seat and the valve flap are at the top of the valve, the valve flap can make the dirt pass in the switch, and has good self-cleaning performance, no dirt trouble.
When the device is just started, there is air and low-temperature condensate in the pipeline. At this time, the trap is fully open, the air and low-temperature condensate are quickly discharged, and the device quickly raises the temperature. When the steam enters the inverted bucket, the inverted bucket generates upward buoyancy, and the inverted bucket is connected with a lever to drive the valve core to close the valve.
There is a small hole on the inverted bucket, which can automatically exhaust air. When part of the steam is discharged from the small hole, the other part of the steam produces condensate, the inverted bucket loses its buoyancy and sinks, and the inverted bucket is connected with the lever to drive the valve center to open the valve. When the steam enters the inverted bucket again, the valve is closed again, and the cycle work and discontinuous drainage.
