The Heaton Brand of valves was originally manufactured by Hattersley Heaton at Nottingham in England. In 1996 the UK factory closed.
Since that time the Heaton range of valves was manufactured for MRC Transmark at manufacturing facilities in China using the latest manufacturing techniques available. HV Brand valves remain manufactured to the API and ASME range of standards with the pressure and temperature ranges defined within ANSI B16.34. Heaton Valves Africa has performed independent audits at the facilities utilized in the production of HV brand valves for the Southern African market.
The HV range of gate, globe, check and ball valves are produced to meet the demanding needs and high specification requirements of the petrochemical industry. To ensure a high standard of manufacturing and Quality Assurance HV Brand valves are subjected to Third party witness testing by an independently contracted inspection authority.
The valves are certified to EN10204 3.1 and exclusively stocked by Heaton Valves Africa. Sizes range from 50mm to 900mm in flanged and butt-welds ends in a wide range of materials and pressure classes.
The HV Brand valves that are currently supplied by Heaton Valves Africa are manufactured in accordance with the European Directive 97/23/EC and pressure equipment directives. They can also be supplied to meet emission requirements of less than 100ppm.
