SAMSON 3331-pneumatic-ANSI regulating valve process control valve

SAMSON 3331-pneumatic-ANSI regulating valve is a high-performance butterfly valve. The following is a detailed introduction:

Basic parameters:

Valve type: butterfly valve.

Applicable media: liquid, gas and steam.

Valve size: NPS 4 to NPS 16 (DN100 to DN400).

Pressure level: ANSI Class 150 to Class 300.

Medium temperature: -10℃ to 400℃.

Structural features: It adopts a wafer-type valve body structure, which can be clamped between DIN and ANSI flanges, which can effectively save installation space and is easy to disassemble and maintain.

Actuator configuration:

Can be combined with 3278 pneumatic rotary actuator, which is a single-acting pneumatic diaphragm actuator with a signal pressure of up to 6 bar, a diaphragm area of 160 or 320 cm², actuation direction (fail open / fail closed) can be selected as required, and an externally adjustable stroke limiter to limit the opening angle.

Can also be combined with BR31a - 2010 pneumatic rotary actuator, which is a single-acting and double-acting piston actuator with a signal pressure of up to 10 bar and a torque range of 5 to 11674 N・m, suitable for demanding scenes such as chemical plants, an opening angle of 90°, and a temperature range of - 40℃ to + 80℃.

Performance advantages:

It has good sealing performance and fluid control performance, can stably control the flow and pressure of the medium, the adjustable ratio can reach 50:1, and the control accuracy is high.

Made of high-quality materials, such as the valve body can be made of carbon steel or stainless steel, the valve plate is made of 1.4581 stainless steel, etc., with high strength, corrosion resistance, high pressure resistance, etc., and long service life.

Accessory options: It can be equipped with a variety of accessories, such as positioners, filter pressure reducing valves, valve position switches, solenoid valves, etc., and different communication protocols, explosion-proof levels and protection levels can also be selected to meet different working conditions and control requirements.
