Spence Engineering 05-01674-00 4" Diaphragm Valve Hycar E2

The Spence Engineering 05-01674-00 Diaphragm-Valve is a 4” high quality control part made of Hycar material for high heat, oil and chemical resistance. This is made for use with E2 HVAC systems and is used to control the flow of steam, air and fluid in high end commercial heating and cooling systems. It operates through the variation in pressure or flow using a flexible diaphragm, which eliminates the use of sliding seals and reduces leakage and maintenance. It is widely used in boilers, heat exchangers and other HVAC control systems as it offers modulation, energy efficiency and protection of the system in thermal control applications.
