Acid-resistant ball valve DN 20 WKS 2g 1.6 MPa, threaded connection APA02060516080

Durable Protection for Installations in Chemical Environments

When acids, alkalis, or other aggressive chemical substances circulate within a system, standard stainless steel is often insufficient. In such cases, valves made from corrosion-resistant materials are critical; they must not only survive but also maintain tightness for years. The WKS 2g series ball valve is a solution specifically designed for these demanding conditions. Its body is constructed from acid-resistant steel, eliminating the risk of rapid material degradation due to chemical erosion. Consequently, this device performs reliably in environments where other valves would quickly fail, ensuring the safety of the entire technological circuit.

Applications and Key Design Features

This device, with a nominal diameter of DN 20 (1/2 inch), is designed for precise flow control in industrial and process installations. Threaded (internal) connections facilitate installation in existing piping systems, eliminating the need for additional transition components. A key design element is the sealing made from PTFE (Teflon). This material exhibits exceptional chemical inertness, meaning it does not degrade even upon contact with strong acids and does not affect the quality of the conveyed medium.

For the installer, operational ergonomics are also important; the valve is equipped with a solid steel handle, allowing for secure and rapid opening or closing of the flow. The total weight is approximately 3.7 kg, which, given dimensions of 11 x 11 x 2 cm, indicates a robust body construction rather than excessive weight that would hinder installation.

Main Application Areas:

• Chemical installations requiring resistance to acids and alkalis.
• Process systems in the food and pharmaceutical industries (where chemical purity is a priority).
• Circuits conveying aggressive process media.
• Installations requiring high tightness in harsh environmental conditions.

Operating Conditions and Technical Application Range

The valve operates at a nominal pressure up to 1.6 MPa (PN16), covering the needs of most standard low- and medium-pressure industrial installations. This is a typical two-way valve intended for full opening or closing of the flow (ON/OFF function), rather than for precise flow regulation. The PTFE sealing material and steel body allow operation across a wide temperature range (depending on the specific type of acid-resistant steel used in production), maintaining seal flexibility even under thermal changes.

It is important to note that during installation, proper tightening of threaded connections must be ensured to avoid leaks resulting from assembly errors; material quality alone cannot replace correct pipe joining techniques. Thanks to the use of acid-resistant steel and Teflon, this valve minimizes the risk of failures caused by intergranular corrosion or general chemical degradation of the sealing material. This is the choice for those who value long-term reliability over the lower initial cost of standard valves.
