SAMSON 3321-IP regulating valve process control valve

Type and use: The 3321 series is a straight-through single-seat control valve suitable for liquid, gas and steam media. It can be used in fields such as machinery and equipment engineering. It mainly plays the role of flow regulation and realizes the control of process parameters such as pressure and temperature.

Technical parameters: The nominal diameter may be DN15-DN100, the rated pressure can reach PN10-PN40, and the temperature range is about -10℃-220℃, but the specific information needs to be referred to the product manual or official information.

Actuator related: This series of control valves can be equipped with pneumatic or electric actuators. If "IP" is related to the actuator, it may be an actuator equipped with a certain protection level or function. For example, the 3372 electro-pneumatic actuator with the 3321 control valve has a protection level of IP54 (with integrated positioner) or IP66 (with 3725 positioner), and the input signal is 4-20mA.

Structural features: Usually composed of a ball valve and an actuator, it can be used with 3372 electro-pneumatic actuators, etc. The actuator may contain two diaphragm boxes, a rolling diaphragm, and internal springs.

Accessories and options: You can choose accessories such as 2N type filters, 2NI type filters, etc. There may also be optional configurations such as noise reduction diverters and insulation sections to meet different working conditions.
