Troublefree Pressure Reducing Valves

COSPECT®’s built-in strainer, Super Cyclonical Effects Separator (SCE) and Free Float® steam trap help prevent scale, rust and condensate from entering the pressure reducing valve (PRV) or reaching the important interior parts.

In particular, the cyclone separator forcibly removes 98% of the condensate from the flow at the inlet side, thereby greatly reducing condensate-induced erosion of parts such as the main valve.

While the standard service life of a PRV for steam is often less than a few years, many TLV COSPECT® users are still using their COSPECT® PRVs more than 10 years after installation. Such long service life is a testimony to COSPECT®'s effectiveness in countering scale and condensate, some of the most common sources of problems for PRVs in steam systems.

Benefits and Features

Improved Quality of Material Being Heated
- Delivers Stable Pressure
  Achieves secondary pressure accuracy within ±0.01 MPa of the set level. Even if the steam flow (load) to the equipment or the primary pressure at the pressure reducing valve changes, the Shock-Absorbing Spherical Piston (SAS) supplies steam at a constant pressure in order to prevent temperature fluctuation downstream.
- Supplies Dry Steam
  The built-in Cyclone Separator removes condensate from steam with a condensate separation efficiency of 98%. Condensate entrained in the steam is removed, and a strainer further removes any scale. The condensate that is separated out is discharged through the built-in Free Float® steam trap.
  The increased quality of the steam contributes to improved heat conductivity.

Easy to Adjust
- Pressure adjustment is simple; just use the cover cap as the adjustment spanner.

Long Service Life
- Rust presents a high risk to vital areas of the system. To eliminate this, all major valve components are made of stainless steel to prevent rust and corrosion. Additionally, the inclusion of a strainer in the piping installation prevents the inflow of rust and other debris, protecting the valve components and contributing to a long service life.

Application Areas

Recommended for processes requiring steam at a stable pressure and processes such as atomizers in which steam comes into direct contact with the product.

Reactor kettles,
Dryers,
Heat exchangers,
Presses,
Steamers
Blowers
Atomizers, etc.
