Proportional Angle Seat Valve 4-20mA positioner 1600/1860
Pneumatic Angle seat valve + Electro-pneumatic positioner. Signal 4-20mA, feedback voltage 24VDC. Valve stainless steel 316L Port is DN32(1 1/4”)
Electrical interface connection Angle Seat Valve หรือ Piston Valve
Specification for the use of waterproof electrical connectors.positioner piston valve
The electrical interface features male and female protrusion and indentation
designs. Please insert it into the waterproof pin male head according to the
S1 and S2 marks. Forcing insertion without proper alignment may cause
the pins to bend and break.

Inspection Issues
The display screen does not light up after the locator is powered on
Ensure the DC24V power supply is connected, and check if the positive and
negative poles are properly connected.
2. The locator is unable to locate the opening and closing of the valve for an
extended period of time
2.1 Check whether the air pressure meets the cylinder pressure requirements,
whether there is any leakage in the air supply pipe, and whether there is any leakage in
the cylinder.
4.2.2 Precautions for connecting to the gas source:
Afilter regulator must be installed before connecting the air source to the positioner.
The operating pressure of the air source should not exceed 0.7 MPa and should be
less than 0.3 MPa; otherwise, the cylinder cannot be opened

General Features
Input Signal: Accepts a standard 0/4-20mA current signal from a controller or control system for proportional control.
Position Feedback: Often includes an optional 4-20mA position feedback output for remote monitoring.
Control Mechanism: Converts the electrical input signal into a pneumatic signal to control the valve's opening, working with an adjustment cone for accurate flow control.
Accuracy: The design, often involving a parabolic or specific control trim, helps establish a linear or proportional relationship between the valve stroke and flow rate for accurate and fast adjustment.
Durability: Positioners are typically designed for tough process environments, with features like IP67 or IP65 protection and robust materials.
Operation: Supports both manual and automatic operation.
Power Supply: Generally operates on a DC 24V ±10% power supply.

****A piston valve is a type of valve that uses the linear motion of a piston within a cylindrical chamber to control the flow of a fluid or gas. They are widely used in a variety of mechanical systems due to their reliability, precise control, and ability to handle high pressures and temperatures.
