HYDRAULIC CONTROL VALVES The automatic control valves are diaphragm valves designed to provide hydraulically driven solutions to pressure, flow and level control applications. Features: Main valve uses globe design for superior control characteristic. Top and Bottom seat rings are used to guide the stem and diaphragm assembly for extended life time and stability. High strength ductile iron body used for lowering the weight and improving long term durability. Stainless steel used for seat and disc retainer ring for corrosion resistance. Easy maintenance without having to remove valve from the main line. Nylon reinforced rubber diaphragm for long term service. Drop tight shut-off capacity. Various pilots and accessories available to offer a large range of control applications. All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance per AWWA C0.

A00 - Remote Float Control Valve. Main Valve. Needel Valve. Ball Valve. P00. Strainer A00 Flexible Joint. Maintains a constant water level; the float pilot will shut off and close the main valve.. The remote float pilot will automatically close when the water level rises to defined level, and opens when water level drops. A0B - Bi-Level Float Control Valve. Main Valve. Restriction. Ball Valve. Bi-level Float Pilot. Strainer. On-Off control. Upper stop - closed tight when the water level reaches high water level.. Lower stop - start to open when the water level drop below a pre-set level.. Controls the water level in the tank and can be adjusted thru the rod stop. HYDRAULIC CONTROL VALVES 7
A00 - Remote Reducing Valve. Main Valve. Needle Valve. P00. Ball Valve. Inlet Pressure Gauge (Optional). Outlet Pressure Gauge (Optional) 7. Strainer 7 A00. Reduces the higher upstream pressure and keep the downstream pressure as per the pilot setting (adjustable).. Independent of the downstream variations of flow or pressure. A0 - Pressure Sustaining/Reducing Valve. Main Valve. Needle Valve. P00. P00. Ball Valve. Inlet Pressure Gauge (Optional) 7. Outlet Pressure Gauge (Optional) 8. Strainer 7 8 Main A0. Reduces the higher upstream pressure and keep the downstream pressure as per the pilot setting (adjustable).. Independent of the downstream variations of flow or pressure.. The sustaining pilot keeps the upstream pressure above the pilot setting to prevent drop of the inlet pressure below the set point. HYDRAULIC CONTROL VALVES 8
AA - Surge Anticipation Valve. Main Valve. Needle Valve. P00. P0C. Ball Valve. Inlet Pressure Gauge (Optional) 7. Strainer 7 Main. The purpose of P0C is to open at low pressure for a rapid relief of high pressure wave.. The pre-open function eliminates the surge during pump abrupt stoppage.. The valve releases excessive system pressure. AA A00 - Slow Opening / Closing Valve. Main Valve. Ball Valve A00. Performs the same function as a check valve.. The valve opens when inlet pressure exceeds outlet pressure and close in case of pressure reversal.. Closing speed can be adjusted with the small valve. HYDRAULIC CONTROL VALVES 9
A00 - Flow Control Valve. Main Valve. Needle Valve. P00. Ball Valve. Orifice Kit. Strainer A00. Maintains a constant flow, regardless of fluctuations of system pressure.. The rate of flow pilot can be flexible, and senses the pressure differential across an orifice plate mounted in the valve outlet flange.. When the level of system pressure changes, the flow pilot responds and modulates the main valve to maintain the desired flow. A00 - Pressure Relief / Sustaining Valve. Main Valve. Needle Valve. P00. Ball Valve. Inlet Pressure Gauge (Optional). Strainer Main A00. Relief: if the system pressure exceeds the preset of the pilot, the valve will immediately open to release excess pressure, and keep the system within safe operating parameters.. Sustaining: prevents upstream pressure (mainline) from dropping below the preset pressure. HYDRAULIC CONTROL VALVES 0
