Design Features & Function The solenoid remote float control valve, also known as electromagnetically controlled remote float valve, is a modified version of the conventional Y-globe or single-chamber remote float valve. It is a diaphragm hydraulic control valve that utilizes the pipeline’s hydraulic pressure as its driving source and can also be remotely controlled electrically. It incorporates a solenoid valve and …

Design Features & Main Applications The single chamber remote float valve is a diaphragm-type hydraulic control valve that has only one control chamber located above the diaphragm. The single chamber design uses line pressure acting from below the valve trim while simultaneously applying pressure through a float mechanism to the control chamber above the diaphragm. The closure member (disc) of …

The remote float valve is a diaphragm-type hydraulic valve that uses the pressure within its own pipeline as its driving force. Equipped with an adjustable horizontal float ball, it regulates water injection to maintain a steady water level—even when flow rates vary. This reliable design makes it ideal for applications such as reservoirs and water tanks where precise liquid level …

What’re Pressure Relief & Sustaining Valves? The pressure relief and sustaining valve is a diaphragm-type hydraulic control valve that is actuated by the hydraulic pressure within its own pipeline. Its key advantage is its dual functionality—it can serve as either a pressure relief valve or a pressure sustaining valve. When operating as a pressure relief valve, it automatically releases any …

At Metalsin, we supply pilot-operated pressure reducing valves for waterworks. Such a pressure reducing valve is a pilot-operated, diaphragm-type hydraulic control valve that utilizes the pipeline’s own hydraulic pressure for operation. Its pilot mechanism regulates the main valve, ensuring that both hydrostatic and dynamic outlet pressures remain stable at the preset value despite fluctuations in inlet pressure or changes in …

At Metalsin, we supply weighted swing check valves that are made in accordance with EN 12334. The weighted swing check valve, also known as swing check valve with weight & lever, is a specialized type of check valve designed to prevent backflow with enhanced control over closure dynamics. Structural Features The EN 12334 weighted swing check valve consists of some …

At Metalsin, we supply resilient seated swing check valves made to EN 12334 for waterworks applications. Resilient seated swing check valves are engineered to prevent backflow in piping systems, ensuring unidirectional fluid flow. Unlike metal-seated swing check valves, which rely on metal-to-metal contact for sealing, resilient seated valves utilize elastomeric materials to achieve a tight seal. Resilient Seated Design The …

Structural Design At Metalsin, we supply EN 12334 ductile iron swing check valves (soft seated & metal seated) for waterworks industry. A swing check valve is an automatic valve that allows fluid to flow in one direction while preventing backflow. Its primary components include: Valve Body: The main housing that contains all internal components and is made from spheroidal graphite …
