“T-Series” Power Ball Valves – The Ladish Way
Ladish will be unveiling it’s newest product and brochure VERY soon. Here’s a sneak peek into our newest metal seated ball valve option – the “T-Series”. CLICK HERE to be among the first to receive our newest publication in your inbox!
The T-Series is a two-piece ball valve designed to incorporate all of the aspects of the Ladish metal seated quarter-turn sealing technology while being produced in quantities to reduce price and lead time. Features include Full Surface (360 degree) lapping of ball to seats for repeatable tight shutoff to all industry standards, live loaded packing, fully supported stem construction, sprayed-and-fused coatings and thermally matched valve trim. The integral ISO direct mounting pad’s engineered design allows for ease of automation. A lever or a T-handle is included for easy manual operation in confined areas with space restrictions. Our flow path through the valve is optimized to give the maximum Cv possible through the given bore sizes.

Ladish utilizes a rigidly secured mounting bracket for actuators, wormgears and levers. The bracket, constructed of heavy plate steel, is welded or bolted to the valve body. The mounting plate is parallel to the bore, and perpendicular to the stem, so there is no misalignment of the operator. Ladish places a heavy metal brushing in the bracket of the valve to guide stem and ensure that the stem does not experience lateral movement if subjected to side loads during operation. If side load occurs, it is absorbed outside the packing chamber and does not deform packing. Deformation of packing caused by side loading is a major cause of stem leakage in quarter-turn valves.
The term “Metal Seated Ball Valve” is widely used for this technology, but the ball and seat coatings that allow the valve to cycle without galling is the real heart of the valve. It is this same coating that is lapped for a Tight Shut-Off and must resist chemical and thermal attack from the process in which the valve is installed. The key to the reliability of the valves in your process is the selection of the right coating for your application, and Ladish engineers are expert in assisting with that selection. Some of the more standard options offered are:
- Spray & Fused – The ball and seat surfaces are coated with a relatively thick layer of hardening material, then the part is heated to “fuse” (similar to welding) the coating to the base material for the highest possible bond strength and lowest porosity.
– Complex Carbides and Borides
– Nickel / Cobalt Based Materials
- HP-HVOF Process – Ladish utilizes a robotically controlled “gun” which applies the coatings at a velocity and energy level that creates a mechanical bond with the base metal.
– Chromium Carbide with Nickel, Chromium or Cobalt Binders
– Tungsten Carbide with Cobalt or Nickel Binders
Once again, Ladish will continue To Mark Progress.
