This construction is suitable for industrial installations where corrosion resistance, external durability and metal actuator protection are required. **Pneumatic 2/2 Way On-Off Control**A pneumatic piston actuator opens or closes the two-port process flow path. The valve is suitable for repeated automatic switching of compatible liquids, gases and steam in industrial equipment. **Threaded Sizes from 1/2 Inch to 4 Inch**The available range includes DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80 and DN100, covering threaded pipeline sizes from 1/2″ to 4″. **Compact Threaded Pipeline Installation**Female threaded process ports support installation without welding clamps or bolted flanges. Customers should confirm whether the required connection is BSP, BSPT, NPT or another thread standard. **1/8 Inch Pneumatic Pilot Connection**The published dimensional drawing marks the actuator-air connection as 1/8″. The exact pilot thread standard and required control pressure should be confirmed before ordering. **Conventional and Water-Hammer-Reducing Flow Options**The drawing identifies high inlet and low outlet as the conventional direction. Low inlet and high outlet is shown as the arrangement intended to reduce water-hammer effects and may require a larger actuator on some sizes. ### Applications **Industrial Steam Systems**Suitable for automated steam switching in heating equipment, laundry machinery, drying systems and process lines when the seat seal, pressure and temperature ratings match the application. **Water and Hot-Water Pipelines**Used in water supply, cooling circuits, washing equipment, heat exchangers and automated cleaning systems that require pneumatic on-off control. **Compressed Air and Gas Control**Applied to compressed-air lines and compatible industrial gas systems where pilot air operates the main process valve. **Cleaning and Process Equipment**Suitable for industrial washing systems, sterilization support equipment, fluid-delivery skids and general processing machinery. **Corrosive or Washdown Environments**The all-metal external construction is useful where plastic actuator housings may be unsuitable, provided the selected stainless steel grade and seal material are compatible with the environment. ### Why Choose HOMIPNEU HOMIPNEU supplies all-stainless-steel angle seat valves, plastic actuator angle seat valves, threaded valves, quick-clamp valves, weld-end valves, flanged process valves, steam solenoid valves and pneumatic control components.

The valve has two process ports and two operating states: open and closed. **What parts are made from stainless steel?**The displayed product has a stainless steel actuator housing and stainless steel angle seat valve body. The exact stainless steel grade should be confirmed for each order. **What sizes are available?**The current product range covers DN15 through DN100, with threaded ports from 1/2″ to 4″. **Is the valve normally closed or normally open?**The displayed actuator has two pneumatic connections, indicating a double-acting configuration. Other required functions should be confirmed according to the supplied version and control circuit. **What is the pneumatic pilot port size?**The current dimensional drawing shows a 1/8-inch pilot-air connection. Confirm whether the supplied thread is BSP, BSPT, NPT or another standard. **Can this valve be used for steam?**It can be selected for steam service when the body grade, seat seal, process pressure, steam temperature and actuator configuration meet the application requirements. **What does the anti-water-hammer option mean?**The page shows low inlet and high outlet as the flow arrangement intended to reduce water-hammer effects. Several sizes use a larger actuator for this installation direction. **Which thread standards are available?**The current page does not specify one fixed standard. Confirm BSP, BSPT, NPT or another required thread before ordering. **What should be confirmed before ordering?**Confirm the DN size, port thread, stainless steel grade, seat seal, actuator function, actuator size, pilot pressure, medium, process pressure, temperature and flow direction. **Does HOMIPNEU support OEM and distributor orders?**Yes. HOMIPNEU supports OEM and ODM supply, bulk orders, private labeling, export packaging and specification confirmation for pneumatic process valves. ### OEM & ODM Support HOMIPNEU provides OEM and ODM support for all-stainless-steel threaded angle seat valves, plastic actuator angle seat valves, quick-clamp valves, weld-end valves, flanged valves, steam valves, pneumatic control valves and related automation components.
