Pressure Reducing Valves (Direct Acting): DR20 | TLV
As a result, the large coil spring contracts and the small coil spring pushes the main valve up. This makes the main valve shut tighter and let less steam pass through. The decrease in steam volume makes the outlet pressure decrease and restores original pressure levels.
The TLV DR20 direct-acting pressure reducing valve provides a more stable secondary pressure than conventional direct-acting reducing valves. The DR20 is designed for a long service life, and is made of stainless steel for superior durability.
