N-Series Isolation Poppet Valves 4.0 Description of N-Series Valve 4.1 Overview Nor-Cal Products N-Series valves are pneumatically operated bellows sealed poppet valves, designed for light weight and compact size as well as robust operation and long life. The pneumatic valve is controlled by a pneumatic cylinder located inside the top of the valve body for extra low profile and envelope size. The valve closes by use of an internal spring. Supplying compressed air to the pneumatic cylinder opens the valve.

N-Series Isolation Poppet Valves 5.2 Valve Installation Every N-Series valve is packaged with plastic protective flange end-caps. Leave these caps in place until the product is ready to be installed in the piping manifold or vacuum system. Even the smallest scratch or nick on the flange sealing surface can significantly compromise the leak integrity of the vacuum system and cause inadequate pump-down performance.
N-Series Isolation Poppet Valves 5.5 Position indicator Electrical Connection BLACK -Ground GREEN - Closed WHITE - Open RED - +24 VDC Input: +5 to +28 VDC Output: NPN Standard PNP Option available on request Figure 5.5.1 6.0 Troubleshooting Please refer to the following possible symptoms and root causes to troubleshoot your N-Series valve. Alternatively, you can contact Nor-Cal technical support at 800-824-4166. In many cases, the N-Series valve problem can be diagnosed and fixed in the field.
N-Series Isolation Poppet Valves 6.2 Valve Will Not Open All The Way or At All Observe the pneumatic connection on top of the valve to watch the valve stem rise and fall. A completely open valve should show the valve stem / push-to-fitconnector interface about 0.4” (10mm) above the top cap of the valve. If the valve does not appear to be opening completely, possible causes include: • Inadequate air supply pressure.
N-Series Isolation Poppet Valves 6.6 Valve Makes Noise Under normal circumstances, the N-Series valve will make a very faint sound when actuated. This sound stems from the spring compressing and coming in intentional contact with the guides inside the pneumatic cylinder housing. If the valve starts making loud scraping or vibrational noises, then a more serious problem has developed. Please contact Nor-Cal technical support at 1-800-824-4166. 6.
N-Series Isolation Poppet Valves 7.1 Replacing O-Ring Seal 1 Remove air fitting, if installed. Install vented screw with large flat washer [supplied in kit] until screw stops. 2 Remove the four button head screws securing the bellows / actuator assembly to the body using a 3/32” hex key. Do NOT overtighten. (This partially opens the valve allowing the bellows /actuator assembly to be removed.) 3 Grasp actuator top and lift bellows /actuator assembly out of body.
N-Series Isolation Poppet Valves 7.2 Valve Rebuild Kit All N-Series valves port size 0.75” thru 2”, use the actuator rebuild kit. The rebuild kit consists of the pneumatic / spring actuator and the bellows assembly. The rebuild kit does NOT include the poppet and bonnet O-rings, solenoid valves or position indicators. These parts should either be reused from the original parts, or they need to be ordered separately (refer to Sections 7.1, 7.3 and 7.4 as applicable).
N-Series Isolation Poppet Valves 5 Solenoid test: Insert air supply line into the straight fitting on the solenoid. Apply 60 to 100 psi air pressure. Valve should not open until power is applied. Verify valve opens with power is applied and closes when power is removed. Alternately you can actuate the solenoid valve by pressing the manual actuation button. Actuation Button 7.
