ATV provides a full range of Nozzle Check valves for production, processing and transmission applications, suitable for pressure up to 2500 psi. 

Nozzle Check valves have typically a full bore design with care to minimize the pressure loss to negligible values while providing high-speed response time. Design is carried out using advanced parametric design tools and solid modelling programs. Valves design undergoes sophisticated structural and fluid dynamic analysis, carried out with FEA and CFA analysis: inner profiles are optimized in order to control the turbulence level and to increase device performances. 

Materials are sourced from qualified suppliers on the base of specifications that reflect the industry standards (API, ASTM, NORSOK, BS, DIN or others), but do also incorporate additional requisitions resulting from long experience.  
ATV designs, manufactures and tests its products in accordance with all the relevant Industry standards and codes (ANSI, API, ASME, BS, ISO, NACE, PED and others). 

ATV stresses its willingness to produce engineered valves; therefore, it welcomes requests for special size, class and design requirements.
