I have been working in the Gas Pipeline industry for 34 years as a field tech and met up with Thomas Allen just over ten years ago. I have learned more about valves in our system, working in conjunction with him, swinging wrenches, from his field knowledge and expertise. From maintenance to trouble shooting, to using them for isolation, We have done valve rebuilds, and used that also as a field training for new employees. The professionalism and customer service is impeccable, which seems to be a dying breed in our industry. The team of field techs are also very good. When you want the best these are the people you want.
