VP 2017
An effective water treatment program is essential to transform scale-forming impurities into non-adhering sludge, preventing energy efficiency loss and potential boiler tube failure. The bottom blow-off process removes non-adhering sludge and accumulated sediment.
Each valve undergoes hydrostatic and seat leakage testing, along with mechanical, metallographic, and 8,000 cycle lot testing to ensure quality. Test reports accompany each order and are stored in TECVAL's asset administration software for traceability.
- Tight Shut Off: The investment casting hardened stainless steel disc and seat ensure a tight shut-off and smooth sliding action, effectively removing boiler scale and cleaning surfaces.
- Durable: Stem packing materials minimize friction, facilitating smoother valve operation and preventing leakage.
- Quality: The TECVAL VP Series is CRN certified, registered in several Canadian provinces.
The valve components are made from materials such as cast iron, AISI 420 hardened steel, bronze, and carbon steel, ensuring durability and performance.
Installation should comply with the ASME Code for Power Piping B31.1-2007, ensuring proper lever clearance for easy access and operation.
Pressure ratings vary based on the model and application, with specific guidelines provided for different boiler types and capacities.
Ordering codes are provided for easy identification of valves and spare parts, ensuring compatibility and ease of maintenance.
TECVAL offers a range of products including quick opening, slow opening, and automatic actuation valves, as well as silencers, pressure vacuum relief valves, and blanketing valves.
TECVAL's factory and head office are located in Bogotá, Colombia, with contact information provided for inquiries.
