API Gate Valve Manufacturer in Italy – Valvesonly Europe

Valvesonly Europe is an API Gate Valve Manufacturer in Italy, specializing in high-performance isolation valves designed for oil and gas, petrochemical, refinery, power, and industrial service applications. Our valves are manufactured in Italy in compliance with API 600, API 602, API 603, and API 6D standards, and certified under PED 2014/68/EU for use in the European market. Each valve is designed for precise operation, reliable sealing, and long service life under demanding process conditions.

Function & Working

An API gate valve isolates flow through the linear movement of a wedge or slab that travels perpendicular to the flow path. When fully open, the unobstructed bore provides straight-through flow with negligible pressure drop. When closed, the wedge or slab seals tightly against the body seats to achieve complete shutoff. Different designs such as flexible wedge, solid wedge, slab, and parallel slide are available to suit various pressure and temperature conditions, including thermal expansion and high cycling service.
