1 CONTROL VALVE SPECIFICATION, PERFORMANCE & DIMENSIONS SECTION 3 1. GENERAL: The 1000 Series Valve is a sleeve style water control valve that is capable of operating in a pressure range from 10 PSI (0.7 bar) to a maximum of 150 PSI (10.3 bar). The specific pressure range shall be determined by the internal rubber sleeve that is selected at the time of valve manufacture. See the valve configuration code form on the following page. The valve shall be designed for optional accessories which may include control devices to accomplish the following purposes: A. Valve shall function for manual open/close operation or remote control when an electric solenoid is provided. Solenoid operation shall be through connected control wires or wireless TWIG and/or hydraulic pressure control. B. Valve shall have pressure control pilot options. A pressure reducing pilot shall be used for downstream pressure control and/or a pressure sustaining pilot for upstream pressure control. C. Valve shall connect to the Rate of flow control. D. Valve shall have ports for control water filters of both internal or external design. E. Valve with pressure control shall have pressure gauge fittings. F. Selected combinations of the above devices. 2. DESIGN A. In the simple form, the valve body shall be a wafer configuration which is designed to fit between two standard flanges or in-between various end connections. The valve flow capacity shall be as shown on the performance graph. Optional body forms shall include tee and elbow style. Materials of the body shall be as shown on the 1000 Series materials guide. B. The internal rubber sleeve shall be formed in the normally closed position and designed so that flow is closed off when equal pressure is applied to both the internal and external surfaces of the sleeve. The valve shall open by internal pressure applied to stretch the rubber sleeve to the open position. C. If equipped with a pressure control, the Nelson 3-way pilot shall be used. The pressure adjustment housing shall have a label to assist the user in setting the pressure properly. The pressure control sensitivity shall be as installed at the factory to match the valve size. D. The valve options will be identified by a configured part number and description code. E. The pressure range and date of manufacture shall be on the valve body.
