<p>A manifold valve, in particular for heating systems with multiple individual circuits, including a valve housing 2 that extends diametrically across the manifold body 6 and has a first end portion with a thread coupling 7 and a second end portion with a cylindrical coupling 8, which coupling portions 7, 8 are accommodated in the corresponding seats 9, 10 formed in the manifold body 6. Sealing is achieved by means of O-ring seals 12, 14 accommodated in the corresponding seats 11, 13. The threaded coupling portion 7 further has a bearing collar 17 on the manifold body 6. Openings 15 are made in the valve housing 2 for the passage of the fluid as well as the water passage opening 5, which co-operates with the moving valve body 7. For connecting the pipe 16 of the corresponding heating circuit, a connection fitting 19 is made in the valve housing 2. The form of the valve housing shown, designed for a thermostat or type valve, that is an automatic valve, is also kept for shutter valves, that is with a manually adjustable moving body which is set up when the heating system considered in each case is adjusted or balanced for the first time.</p> |
