Ball Valves

ANCORP’s high vacuum ball valves consist of a body, stem, ball, and flanged end caps machined from corrosive-resistant 316L stainless steel. Fluoroelastomers are used to seal the stem and end caps from atmosphere while the PTFE seats cold flow around the ball to isolate the process when closed. The valve is opened and closed manually or pneumatically by ¼ turn, quick actuation. PTFE sealing surface helps to protect it from deposition, maintaining a clean dynamic seal to prevent failure due to contamination.

Patented Extended LIfe (XL) Technology

ANCORP’s innovative engineers have developed the Extended Life (XL) Stem Design in response to the challenges faced by leading OEMs in today’s harsh coating processes. This patented stem design extends the stem seal life of our high vacuum ball valve by 10 times compared to traditional designs. With fewer wetted components and a fully stabilized stem, the XL ball valve minimizes maintenance requirements, reduces tool downtime, and increases throughput.

ANCORP’s commitment to continuous improvement and innovation has solidified its position as a leading provider of high vacuum ball valves.

Superior Seal Design

Our high vacuum ball valves feature fluoroelastomer seals to effectively seal the stem and end caps, safeguarding against atmospheric contamination. The PTFE seats around the ball provide excellent cold flow characteristics, ensuring optimal isolation of the process when closed. This reliable sealing mechanism protects the valve from deposition and maintains a clean dynamic seal, preventing failure due to contamination.

Quick Actuation: The valves can be effortlessly opened and closed either manually or pneumatically with just a ¼ turn, enabling quick and efficient operation. This saves valuable time during critical processes and enhances productivity.

Applications

The corrosive-resistant, fast-actuating design of ANCORP’s vacuum ball valves makes them ideal for isolating reactors, traps, and scrubbers on vacuum process tools. Due to the inherently simple design of the ball valve with its fewer wetted components, the valve is less likely to form buildup from byproducts.  In many coating operations such as etching of CVD, PCVD, and MOCVD, byproduct buildup poses a significant challenge. Metal, plastic, or glass particles deposit in vapor form inside and around chambers, valves, and other vacuum components, diminishing efficiency and conductance. This ultimately leads to valve failure. Conductance limiters, including chlorosilane polymers, siloxane polymers, and silicon dust, exacerbate byproduct buildup.

Not only does the design of the valve assist in this matter, but it is easily heated to reduce the possibility of buildup. By maintaining high foreline/exhaust temperatures through heating and ensuring process uptime criticality, ANCORP’s high vacuum ball valves contribute to reducing costs and enhancing overall process efficiency.
