Q and BQ valves are supplied as three individual component parts: the thermostatic element, the valve body, and the replaceable cartridge or orifice. The interchangeable nature of the Q and BQ family make it ideal for reducing inventory, while increasing valve options – so the right valve is always on hand.
Q and BQ brass body type valves feature Sporlan’s traditional knife edge, metal-to-metal thermostatic element to valve body construction, which ensures a leak-proof joint.
Sporlan’s selective thermostatic charges are specifically designed for low temperature, medium temperature, and air conditioning applications. The elements are manufactured with a large flat diaphragm to reduce diaphragm stresses and provide precise control. The installer is able to select the best possible thermostatic charge for the application because the Q and BQ valve bodies and thermostatic elements are supplied as independent components.
Refrigerant flow through the valve port opposes the pin movement in all Type Q and BQ valves. This provides improved stability at light loads, when the pin modulates to a position close to the port. The liquid flow enters near the top of the valve body, which has a warming effect on the thermostatic element and minimizes the potential for charge migration.
The Type Q and BQ valves are available with flare or sweat connections and all feature adjustable superheat.
