Steam Let Down Valve

For High Cycle, Steam, Let Down
and Purging Applications.

Dramatically increase the productivity of your high cycle steam processes with a valve that outperforms the others.

Applications:

Vegetable* and fruit peeling and deskinning
Can sterilization
Steam ejectors
Emergency steam purging
Distilleries
Shellfish processing

In processes involving rapid high cycle steam treatment, purging and dumping, the first equipment casualties have historically been the valves. Thus, many commercial and industrial batch process systems, designed to operate non-stop 24 hours a day have been frequently idled to repair leaking and steam damaged valves.

Until Now! The Worcester Controls Automatic Steam Let Down Valve provides reliable on-off operation in such diverse operations as sterilizing, emergency purging, dumping, vegetable and fruit peeling, skinning and cooking. These valves can operate over one million cycles with opening and closing speeds tuned to your particular process.

One example of such a high cycle process is automatic potato peeling. As shown in the diagram below, saturated steam at 250 psi is blasted into a steam peeling vessel loaded with raw potatoes. The vessel is rotated for a short period. Then the steam (with condensate, grit and juice) is exhausted through a second valve to a recovery unit. Automated plug and butterfly valves, traditionally used in these processes fail within three to six months. Worcester Controls valves easily last a full year. Then, a simple replacement of seats and seals from a distributor stocked repair kit prepares the valve for another full year of non-stop operation.

Worcester's Steam Let Down Valves mate with ANSI Class 300 flanges and are specially designed to take the rigors of high cycle operation and high pressure drop, steam and fluids with entrained solids, caustics and abrasives. Rapid, controllable actuation is provided by Worcester's Series 39 pneumatic or Series 75 electric actuators.
