### Product Features

**Pneumatic 2/2 Way On-Off Control**The valve uses a pneumatic actuator to open or close the two-port flow path. It is suitable for automated process lines where repeated fluid switching is required without manually operating the pipeline valve.

**Plastic Pneumatic Actuator**The engineering plastic actuator housing provides a compact and lightweight operating unit above the angle seat valve body. The required actuator size and pilot configuration should be selected according to valve diameter, operating pressure and control function.

**Threaded Sizes from 3/8 Inch to 4 Inch**Available nominal sizes range from DN8/DN10 through DN100, covering common threaded pipeline connections from 3/8″ to 4″. This allows one product family to support both compact equipment and larger process pipelines.

**BSPT, BSP and NPT Thread Options**The valve can be supplied with British tapered pipe thread, BSP parallel thread, NPT or other customized thread standards. Customers should confirm the required thread system instead of selecting only by nominal inch size.

**Angle Seat Body for Efficient Flow**The angled internal flow path is commonly used to provide a relatively high flow rate with lower pressure loss than more restrictive shut-off valve structures. Actual flow capacity depends on DN size, seat diameter, pressure and supplied body design.

**Conventional and Water-Hammer-Reducing Installation**The dimensional drawing identifies a conventional high-inlet/low-outlet arrangement and a low-inlet/high-outlet arrangement intended to reduce water-hammer effects. Final flow direction must match the selected valve function and installation instructions.

### Applications

**Industrial Steam Pipelines**Suitable for steam supply switching in heating systems, laundry equipment, cleaning machinery, sterilization support systems and process equipment when the body, seat seal, pressure and temperature ratings are suitable.

**Water and Hot-Water Systems**Used in water supply, drainage, washing equipment, cooling circuits, heat exchangers and automated cleaning systems requiring pneumatically controlled shut-off.

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

**Filling and Packaging Machinery**Suitable for auxiliary water, air, steam and cleaning-fluid circuits in filling equipment, packaging machines and automated production lines.

**Industrial Process Equipment**Used in textile machinery, chemical equipment, beverage equipment, temperature-control systems and general fluid-handling machinery after confirming medium compatibility.

Official angle seat valve documentation commonly lists liquid, steam and gas service, but suitability is always dependent on the exact valve body, seat seal, pressure and temperature rating.

### FAQ

**What is a plastic actuator pneumatic angle seat valve used for?**It is used for pneumatically controlled on-off switching of air, water, steam, gas and compatible fluids in industrial pipeline systems.

**Is this a 2/2 way valve?**Yes. An angle seat shut-off valve normally has two process ports and two operating positions: open and closed.

**Is the valve electrically operated?**The main valve is operated by compressed pilot air. An external solenoid pilot valve can be added when an electrical signal is required to control the pneumatic actuator.

**What sizes are available?**The current product range covers DN8/DN10 through DN100, with threaded connections from 3/8″ to 4″.

**Which thread standards are available?**BSPT, BSP and NPT options are listed on the product page. Other thread standards may be customized according to the order requirements.

**Can this valve be used for steam?**Angle seat valves are commonly used for steam service, but the actual body material, seat seal, actuator temperature limit, pressure rating and steam temperature must be confirmed for the supplied version.

**What is the difference between conventional and anti-water-hammer installation?**The page drawing shows high-inlet/low-outlet as the conventional arrangement and low-inlet/high-outlet as the water-hammer-reducing arrangement. Installation must follow the selected control function and approved flow direction.

**Is the valve normally closed or normally open?**The control function cannot be determined from the page title alone. Confirm whether the required version is normally closed, normally open or double acting before ordering.

**What should be confirmed before ordering?**Confirm the DN size, port thread, valve-body material, seat seal, control function, pilot pressure, working medium, process pressure, temperature, installation direction and required quantity.

**Does HOMIPNEU support OEM and distributor orders?**Yes. HOMIPNEU supports OEM and ODM supply, private labeling, export packaging, bulk orders and configuration confirmation for pneumatic angle seat valves.
