SK Valves Groups

Past, Present and Future of SK VALVES

SK VALVES GROUPS is composed of three affiliated companies: " SHYE KUANG VALVES MFG CO., LTD", "EN IN ENTERPRISE CO., LTD.' and "BITOU TECH CO., LTD."

SHYE KUANG VALVES MFG CO., LTD (hereinafter as "SK")  was establied in 1966 in Kaohsiung. Initially, its main products were the casting parts; since 1974 it started to produce gate valves, hydrants and pipe line parts and became the supplier of Taiwan Water Corporation. In 1991,  EN IN ENTERPRISE CO., LTD (hereinafter as "EI") was founded in Pintung. Both SK and EI acquired ISO90001 Certificate in 1998. In 2010,  BITOU TECH CO., LTD. (hereinafter as "BT") was established which is responsible for repairment/maintainance projects in connction with valves and pipe line systems. In order to provide 24-7 service in Taipei, BT has a working office and an engineering team stationed in Taipei City. (SK and EI also have their own engineering teams serving across the country). In 2016 EI became the supplier of 3600mm Biplane Butterfly Valves (2 sets) for Shihmen Reservoir. This was also the milestone for Taiwan government authorities as they selected the domestic manufacturer to supply such equipmemt for the first time. Those two 3600mm Bi-Plane Valves are still well functional right now. Since 2000 SK has become a constant supplier of customers in the US. In respose to high deamnd of production capacity, SK and EI started to expand the cover of facilites and introduced new furnace, solar panel as well as energy storage system in 2022. By doing so, we not only increased the producion efficiency significantly, but also decreased the energy consumption and the relaince of  purchased electricity. In 2025, for the reason of business sustainability policy and compling with the government ESG regulations, EI published the Green House Fas Inventory Report.

To this day, SK VALVES GROUPS still consistently dedicates to improving and developing the products and service, so that we can satisfy the demand of customers either domestic or overseas with professional solutions and high quality products. We are proud to say that our expertise is trust worthy.
