Bolted ball valves are easy to install
15 Jan 2000
Hoke International's 7-series bolted ball valves are designed with an array of features to extend operational life and reduce maintenance costs, says the company. The valves are complete with seats and seals, which reduces the amount of work need to install, remove and maintain them.
The valves are made from 316 stainless steel as standard, and are available in imperial and metric sizes from 1/4 to 1in and 6-25mm. The chevron stem seals self-adjust for leak tightness, and have been independently tested to over 100 000 cycles, the company says.
Safety features include a blowout-proof stem and grounding stem to prevent static discharge, with options such as a trip-proof oval handle and handle lockout device.
