Hydro Pneumatic supplies high-quality actuated and manual gate valves to many specifications.
Our actuated and manual gate valves feature a threaded packing retainer that enables maintenance of the needle bearings or stem pins while the valve is under pressure.
Foreing material is prevented from coming into contact with the stem packing by a specialised wipper ring, which helps to ensure stem alignment. Furthermore, a multi-purpose fitting design permits lubrication of the gate and seat assembly, and vents trapped pressure after stem back-seating.
The selective stem backseat ensures that the gate valve can be backseated against the bonnet to allow for replacement of stem packing, even while the valve is under pressure. A bi-directional, spring-loaded and pressure energised seat maintains constant gate-to-seat contact for low pressure sealing.
Other components include a safe and reliable body bonnet and a gate guide that allows for extended gate skirts.
Hydro Pneumatic's gate valves are made from are made from PSL 1-4 material for H 2 S and CO 2 service in accordance with NACE MR-01-75, latest edition. They are manufactured according to API specification 6A, 16th Edition.
Hydro Pneumatic has developed a quality assurance and control system that accords with major international standards including ISO 9001, PED, ATEX, API-6A, API 6D, Quality System API-Q1 and API (American Petroleum Institute).
Possessing decades of manufacturing experience, Hydro Pneumatic was formed in 1968 in Fiorenzuola (Piacenza, Italy). Since then, the company has become well known for its design and engineering of high-quality, reliable equipment for the offshore industry.
