Didtek F316L Pneumatic Ball Valve

Product Overview

"F316L" usually refers to the valve body whose main material is ASTM A182 F316L stainless steel. This material contains molybdenum, thus it has excellent corrosion resistance and is particularly suitable for handling corrosive media. Pneumatic ball valves use compressed air as power to drive actuators to achieve rapid opening, closing or adjustment of the valve.

Drive mode: Pneumatic (compressed air)

Connection methods: flange, wafer, welding, clamp (sanitary grade), etc

Structural form: Floating ball or fixed ball; Two-piece or three-piece

Sealing material PTFE (polytetrafluoroethylene) : General choice, corrosion-resistant. Others such as PPL are also common.

The nominal diameter coverage is wide, commonly ranging from DN10 to DN100 or larger

Common pressure grades include PN16, PN25, PN40, etc

The applicable media include water, gas, oil, acidic or alkaline corrosive liquids/gases, steam, etc

The gas source pressure is usually 0.4 to 0.8 MPa

The applicable temperature varies depending on the sealing material. For PTFE seals, it is approximately -29℃ to 200℃

The design features may include fireproof structure, anti-static structure, valve stem anti-blowing, ISO 5211 high platform, etc

Functions and Features

Strong corrosion resistance: The core material, F316L stainless steel, can effectively resist the erosion of various corrosive media.

Quick opening and closing: Pneumatic drive can achieve rapid opening and closing at a 90-degree Angle, making it suitable for applications that require frequent opening and closing or quick cutting off.

Reliable sealing: Utilizing soft sealing materials such as PTFE, it is easy to achieve zero leakage.

Automation control: It can be easily integrated into an automation control system in conjunction with accessories such as solenoid valves, limit switches, and positioners.

Safety design: Many products are equipped with fireproof structures (which can maintain a certain degree of sealing in case of fire) and anti-static structures (which can discharge the static electricity generated by friction between the ball and the valve stem).

Typical application industries

This type of valve is widely used in process industries that require corrosion resistance and automatic control:

Chemical engineering and petrochemicals: Handling various corrosive media such as acids, alkalis, and solvents.

Pharmaceuticals and bioengineering: Especially sanitary pneumatic ball valves, used in environments with high requirements for aseptic and dust-free conditions.

Food and beverages: The material and polishing treatment comply with hygiene standards.

Water treatment and environmental protection: Applicable to dosing systems, wastewater treatment and other links.

Vacuum system: Specially designed ball valves can be used for medium flow control under vacuum conditions.
