The Sporlan Q & BQ series are replaceable cartridge style valves designed for small refrigeration systems, such as refrigerated cases, coolers, and freezers. The externally equalized versions of these valves are ideal for air conditioning and heat pump systems.
BQ valves are balanced ported, engineered specifically for systems with a wide range of operating conditions and may be applied on bi-directional applications. Q & 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 & BQ family make it ideal for reducing inventory, while increasing valve options - so, the right valve is always on hand.
BODY FEATURES
Q & 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.
SELECTIVE CHARGES
Sporlan 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. And, because Q & BQ valve bodies and thermostatic elements are supplied as independent components, the installer is able to select the best possible thermostatic charge for the application.
INTERNAL PORT DESIGN
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. Additionally, charge migration, is reduced or eliminated by the Q & BQ valve design. By engineering the liquid flow to enter through the top of the valve body, the liquid refrigerant warms the thermostatic element and minimizes the potential for charge migration.
