The HOMIPNEU page confirms the size range, available flange standards, dimensional data and 1/8-inch actuator-air connection. Pneumatically operated angle seat valves generally use a two-way body and piston actuator for shutting off liquids, gases or steam; the exact medium compatibility depends on the supplied body, seat seal and operating limits.

**Flange Standard:** HG5010-58 / PN10 / PN16. PN25, GB/T 9113, HG20593, ISO, DIN, JIS, and other standards can be customized according to customer requirements.

### Product Features

**All Stainless Steel Construction**The valve combines a stainless steel pneumatic actuator with a stainless steel flanged angle seat body. This all-metal structure is suitable for demanding process environments where corrosion resistance, washdown durability and external actuator protection are important.

**Pneumatic 2/2 Way On-Off Control**The pneumatic piston actuator opens or closes the two-port process passage. Industrial angle seat valves commonly use this structure for automatic shut-off of compatible liquids, gases and steam.

**DN15 to DN100 Size Range**The published range includes DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80 and DN100, allowing selection for equipment pipelines and larger industrial process lines.

**Multiple Flange Standards**Standard flange options include HG5010-58, PN10 and PN16. PN25, GB/T 9113, HG20593, ISO, DIN, JIS and other standards can be customized according to pipeline and project requirements.

**Stainless Steel Pneumatic Actuator**The stainless steel actuator is intended for demanding industrial environments. Official industrial valve documentation notes that stainless steel pneumatic actuators are used where cleanability, robustness and resistance to challenging surroundings are required.

**Conventional and Anti-Water-Hammer Flow Options**The published drawing identifies high inlet and low outlet as the conventional flow direction. Low inlet and high outlet is shown as the arrangement intended to reduce water hammer; larger actuator sizes are specified for some nominal diameters in this configuration.

### Applications

**Industrial Steam Systems**Suitable for automated steam shut-off in heating equipment, laundry machinery, drying systems and process lines when the body material, seat seal, operating pressure and steam temperature match the application.

**Water and Hot-Water Pipelines**Used in water supply systems, cooling circuits, heat exchangers, washing equipment and automated cleaning systems requiring pneumatic pipeline control.

**Compressed Air and Gas Control**Applied to compressed-air lines and compatible industrial gas systems where a pneumatic pilot signal controls the main process valve.

**Cleaning and Washdown Equipment**The stainless steel actuator and valve body make the product suitable for equipment exposed to moisture or regular external cleaning, provided that the selected seals and accessories meet the environment.

**Industrial Process Machinery**Suitable for textile machinery, filling equipment, temperature-control systems, process skids and other automated fluid-handling installations.

Industrial stainless steel angle seat valves are commonly used for liquid, gas and steam shut-off, but final suitability must be verified using the actual material, seal, pressure and temperature specifications of the supplied model.

### FAQ

**What is an all stainless steel pneumatic flanged angle seat valve used for?**It is used for pneumatically controlled on-off switching of air, water, steam, gases and compatible process fluids in industrial pipelines.

**Is this a 2/2 way valve?**Yes. A standard pneumatic angle seat shut-off valve uses two process ports and two operating positions: open and closed.

**What parts are made from stainless steel?**The displayed product has a stainless steel pneumatic actuator and a stainless steel angle seat valve body. The sample shown on the page is marked 304, DN80 and PN16.

**Is every size made from 304 stainless steel?**The displayed DN80 sample is marked 304, but the page does not establish 304 as the fixed material for every size and configuration. The required stainless steel grade should therefore be confirmed before ordering.

**What sizes are available?**The published range covers DN15 through DN100.

**Which flange standards are available?**The page lists HG5010-58, PN10 and PN16, with PN25, GB/T 9113, HG20593, ISO, DIN, JIS and other standards available for customization.

**What is the pneumatic pilot port size?**The dimensional drawing shows a 1/8-inch pneumatic pilot connection. The exact thread standard should still be confirmed for the supplied version.

**Can this valve be used for steam?**Stainless steel pneumatic angle seat valves are available for steam applications, but the actual seat seal, process pressure, steam temperature and actuator configuration must match the operating conditions.

**Is the valve normally closed or normally open?**The current HOMIPNEU page does not specify one fixed control function. Normally closed, normally open and double-acting functions are established options for pneumatic industrial seat valves, so the required configuration should be confirmed when ordering.

**What does the anti-water-hammer option mean?**The page drawing identifies low inlet and high outlet as the arrangement intended to reduce water-hammer effects. The actuator size must be selected according to nominal diameter, pipeline pressure and flow direction.

**What should be confirmed before ordering?**Confirm the DN size, flange standard, pressure class, bolt-hole dimensions, stainless steel grade, seat seal, actuator function, actuator size, pilot pressure, medium, operating pressure, temperature and flow direction.

**Does HOMIPNEU support OEM and distributor orders?**Yes. HOMIPNEU supports OEM and ODM supply, customized flange standards, bulk orders, private labeling, export packaging and specification confirmation.
