The pneumatic control valve essentially consists of:
Type 3510 Micro-flow Valve and
Type 3271-5 Actuator or optionally Type 3277-5 Actuator.
The Type 3510 Micro-flow Valves are available either as:
Globe valves or
Angle valves.
Their valve bodies have either:
Screwed connections with G or NPT thread, Welding ends or flanges.
Stainless steel is used as the standard body material. However, A wide variety of special materials can also be used on customer Request.
Principle of operation
The process medium flows through the micro-flow valve in the Direction indicated by the arrow. The position of the valve plug
(3) determines the cross-sectional area of flow between the seat
(2) and the plug.
The plug stem (6) is connected to the actuator stem (8.1) via the Stem connector (7) and sealed with an adjustable packing (4).
To comply with stricter environmental emissions requirements, The valve can be equipped with a double-walled metal bellows
(10).
The anti-rotation device (13) prevents loosening of the screw Connection between the valve body (1) and the bonnet (5) or the Intermediate piece (9).
Fail-safe position
Depending on how the springs are arranged in the actuator (8)(see Data Sheet T 8310-1 EN for details), the control valve has
Two different fail-safe positions:
Actuator stem extends (FA)
The valve is closed upon air supply failure.
Actuator stem retracts(FE)
The valve is opened upon air supply failure.
