Armstrong TVS 1100 trap valve station includes a built-in piston-style isolation valve, a stainless steel strainer, and a bimetallic steam trap. The space-saving design significantly reduces the number of potential leak points, cuts installation time and costs, and provides years of reliable steam isolation service. The TVS-1100 series utilizes advanced piston seal technology and a compact design to deliver safer and longer-lasting steam isolation.

Key Features

• Single Valve Operation: Eliminates the need for auxiliary isolation valves, reducing the number of potential leak points and resulting in a more compact, space-saving design.
• Dual Seal Operation: The piston valve is seatless and contains two graphite and stainless steel sealing rings. These rings seal the valve stem and act as the valve seat, ensuring long-term prevention of steam leaks to the atmosphere and downstream piping.
• Built-in Strainer: Eliminates dirt and particulates from the steam during operation.
• Bimetallic Air Vent Capsule: Easily vents air and condensate during system startup.
• Seal Integrity: Resilient disc springs apply continuous pressure to keep the upper and lower sections of the valve sealing rings compressed. Keeping the sealing rings tightly pressed against the piston and valve body ensures complete seal integrity.
• In-line Repairable: All sealing valve components can be replaced in-line quickly and conveniently.
• Long Service Life: The piston valve design ensures reliable actuation even after years of non-use.
