Accessory Product Submittals: 1/2" - 2"

PRO Hydronic Specialties offers a full line of standard and extended P/T ports, air vents, hose end drain valves, full and reduced port ball valves, stainless steel braided hoses, unions and butterfly valves for all applications. As with the entire PRO Hydronic Specialties offering, we have engineered features and benefits into our accessory products to add differentiation and specifiable aspects.

Integral Extended Accessories

We have redesigned both our Hose End Drain Valve (H1) and our Manual Air Vent (AV) to incorporate an integrated extension piece onto the actual accessory. In times past when extended options were laid out for chilled water insulation clearance, accessory extenders were used to accomplish the task. This required the installation of the extender onto the accessory, which meant more labor and inventory costs.


Extended Handle w/ Integrated Vapor Seal

PRO Hydronic Specialties is very excited to introduce the next evolution in Extended Handles. Our engineering department has been working overtime on this project. We didn’t just want a better extended handle for our valves; we wanted features and benefits which could be specified – invoking TRUE differentiation from our competitors. Most extended handles rotate as an entire assembly when the handle is turned. Once the extension assembly rotates (post insulation), that rotation breaks the vapor barrier between the handle extension surface and the actual insulation. The thermal barrier is now compromised and will allow the handle to sweat. This sweating allows the interior of the insulating material to become saturated with moist vapor which can cause mildew and or mold! So, what is an Integrated Vapor Seal, and how does it help the system you ask? Without getting too technical, it is essentially the process of thermal diffusing, or decoupling of thermal energy transmitted through conduction across metal surfaces. We have designed a handle that will not sweat, and will not compromise the thermal barrier of the insulation once applied to the valve.
PRO Hydronic Specialties design is essentially a handle inside a handle. With a proprietary design on the stem extension, which allows for a vapor break, along with a thermal diffuser – see illustration:
