Technical Overview & Engineering Specifications
The Model 100X Diaphragm Remote Float Level Control Valve Engineering Datasheet is an authoritative engineering and procurement specification published by Quanzhou Baoming Hardware Products Co., Ltd. (Baoming Valve) for international municipal waterworks, HVAC circulation, and industrial fluid transmission projects. Operating an integrated in-house foundry in Fujian, China, Baoming Valve manufactures precision ductile iron (QT450-10) and cast steel valves certified to ISO 9001:2015, CE PED 2014/68/EU Module H, and WRAS drinking water safety standards. Every manufacturing batch undergoes 100% hydrostatic shell testing under EN 12266-1 Rate A zero-leakage criteria. Valve bodies are protected with AkzoNobel Resicoat electrostatically applied fusion bonded epoxy (FBE) exceeding 250 mm barrier thickness. Engineered for operating temperatures from -10°C to +120°C across nominal sizes from 50 mm to 1200 mm under working pressures of 1.6 MPa and 2.5 MPa. Baoming Valve provides complete EN 10204 3.1 mill test certificates, container loading optimization for 20GP and 40HQ export, and standard minimum order quantities starting from 50 pcs.

Self-Contained Automated Reservoir Water Level Management
The Model 100X valve uses liquid level in the storage tank to actuate a small remote float pilot. When the water level reaches the setpoint, the float closes the pilot, pressurizing the upper diaphragm chamber and smoothly shutting off main inflow without hydraulic shock.
Modulating and On/Off Level Control Capabilities
Available in both modulating (continuous inflow matching discharge) and bi-level on/off configurations (opening at low level and closing at high level), preventing frequent pump cycling.
Zero Electrical Infrastructure Requirement
Because the valve operates completely on hydraulic line pressure, it provides foolproof reliability in remote mountain reservoirs and municipal water towers lacking electrical grid power.
