DN20 PN40 1-Piece 2-Way Stainless Steel Modulating Electric Flanged Ball Valve 24 V AC/DC

This JP Fluid Control modulating electrical actuator is offered in combination with a TamesonPRO 1-piece 2-way flanged ball valve. It can turn the valve from 0-90 degrees with an operating torque of 40 Nm (higher break torque so please see the manual) in a time of 13 seconds. It requires a supply voltage of 24 V AC/DC, has a duty cycle of S2, and comes with a visual positioning indicator on top of the unit to clearly see valve position. As a modulating actuator, it is equipped with a digital positioning system (DPS) meaning it can position the valve anywhere between 0-90 degrees. It requires a control signal of 4-20 mA (and 0-10V, 2-10V) for positioning.

The valve features a 20 mm bore size and DN20 flange connections. It is suitable for medium temperatures from -29°C to 160°C (-20°F up to 320°F). The valve can handle pressures of up to 40 bar at 20°C (579 psi at 68°F). The valve body and the ball are made of stainless steel 1.4408 with a PTFE seal, making it suitable for various aggressive and corrosive media. The Kv value is 48 m³/h (Cv = 55.5 gpm). Kv expresses the flow rate of water in m³/h at a pressure drop of one bar. With the actuator`s durable polyamide (PA) housing, it gives the unit a protection of IP67 for an environment temperature of -10°C till 50°C (14°F till 122°F).

Before connecting the actuator, please read the manual carefully.

Pros:

• It is a modulating actuator with a digital positioning system (DPS) to position the valve anywhere between 0-90 degrees with a control signal of 4-20 mA
• It has a robust IP67 housing
• It has a clear visual position indicator to see the valve`s state
• Suitable for aggressive media due to the 316 stainless steel (1.4408/CF8M) housing and bal
• lMax pressure of up to 40 bar at 20°C (579 psi at 68°F)

Cons:

• In comparison to a pneumatic actuator of the same size, the operating speed is slower

Applications

This valve can be used in combination with gases and fluids. The valve is durable and suitable for different aggressive and corrosive media. The maximum pressure at room temperature is 40 bar (579 psi), at higher temperatures the maximum allowed temperature decreases. The temperature range of the medium lies between -29°C to 160°C (-20°F to 320°F). At high temperatures, it is recommended to install the valve in a ventilated area. It is allowed to install the valve in a humid environment provided that all parts, like an appropriate electrical cable, are correctly fixed. Some examples of applications for this valve are HVAC, irrigation, industrial automation, water management.

Electrical Wiring Diagram

The actuator features a 10-terminal wiring system split between essential power and optional feedback functions. For basic operation, Terminals 1, 2, and 3 provide a ground and a 24V AC/DC power supply with automatic voltage detection. Terminals 4 and 5 receive a modulating input signal, which is set to 4-20 mA by default but can be configured to 0-10V or 2-10V. For remote monitoring, Terminals 6 and 7 provide a continuous position feedback signal, typically 4-20 mA. External voltage must never be applied to these feedback pins to avoid permanent damage. Finally, Terminals 8, 9, and 10 use a common source to provide discrete "Open" or "Closed" status confirmations via limit switches.

Assembly

Make sure that the position of the ball and the actuator are properly set before assembly. The actuator is provided with two adapters to connect the actuator to the valve shaft. Mount the actuator to the valve with the provided bolts. There should be no play between both flange. Use our fittings range for the connection between the pipe and the valve.

Note: This product is delivered in separate parts, but with the required mounting accessories.
