VMS stocks both pressure balancing and thermostatic shower valves for same day shipping in both 3 port and 4 port designs. Pressure balancing valves, also called mechanical or anti-scald valves, are the most common types of shower valves. A pressure balancing valve is designed to rebalance the water pressure to keep the shower from becoming excessively hot. The mechanism contains pistons or diaphragms built to move with fluctuations in water pressure to balance the hot and cold water supplies. These can keep the water temperature constant within 2-3 degrees Fahrenheit. Most pressure balancing valves have a single control and a handle. Water becomes warmer or colder when the valve is turned left or right.
Thermostatic valves are designed to maintain both water pressure and temperature. The thermostatic valve mechanism contains a thermos-sensitive element that adjusts the flow of hot or cold water based on changes in temperature. Many thermostatic valves include a dial that allows users to preset the water temperature.
