This brass normally closed G 1" angle seat piston valve provides reliable shut-off control for gases and fluids. The seat and spindle seal are respectively PTFE/NBR. Suited from 0 to 16 bar and temperatures from -20 up to 85°C. The valve operates with compressed air of preferably 6 bars. Excellent flow rate thanks to the Y-shaped design. Tip: for fast liquid flows, select ‘closing against flow’ valves to prevent water hammer.

This normally closed G 1" angle seat piston valve provides reliable shut-off control for gases and fluids. The main valve body is made of brass with a seat and spindle seal of respectively PTFE/NBR. Suited for media from 0 to 16 bar and temperatures from -20 up to 85°C. The valve operates with compressed air of preferably 6 bars (min 4, max 10), a pneumatic 3/2 valve is required to control the air supply. Excellent flow rate thanks to the Y-shaped design. Tip: for fast liquid flows, please select ‘closing against flow’ valves to prevent the risk of water hammer.
The AL2 series is an extensive range of 2-way angle seat piston valves with a wide variation of materials, sizes and functions to suit a wide range of applications. They are characterized by excellent flow rates and can be used under though conditions. They are excellent alternatives to ball valves. They can be used in applications where the most standard solenoid valves would fail, such as thick, viscous, or even slightly contaminated media.
The valves are available in normally closed (NC) and normally open (NO) versions. They return to their rest (normal) position by spring force and change position by filling the control cylinder with compressed air of preferably 6 bars (between 4 and 10 bars). An extra 3/2 pneumatic (solenoid) valve must be used to control the air supply.
The valves are available in brass or stainless steel. The seat sealing is PTFE by default. Some versions have FKM seat seals, which is a more flexible material and provides improved sealing properties. The stainless-steel valves have a control cylinder of nickel-plated brass and can optionally be provided with a stainless steel control cylinder. Some versions have an aluminium actuator. The standard flow direction is in the same direction as the closing direction of the valve. When using liquids (not gases) at high flow velocities, there is a risk of water hammer. Using the valve in reverse direction reduces this risk, select if necessary valves that have the ‘close against flow’ designation.
