Single Door Foot Valve (K-518 / K-519) – Plumbing Applications
The Single Door Foot Valve is a highly reliable non-return valve designed to permit fluid flow in one direction only and automatically close when the flow reverses. Installed at the suction end of pumping systems, this valve plays a crucial role in maintaining pump prime, preventing backflow, and ensuring smooth and efficient operation of plumbing and water supply systems.
Manufactured in strict conformity with IS:4038, the Single Door Foot Valve is built for durability, safety, and long service life. The valve is available with rubber seating, providing excellent sealing performance and minimizing leakage even under fluctuating pressure conditions. It is offered in both swing type and lift type designs, allowing flexibility to suit various installation and flow requirements.
The swing type foot valve is available in screwed connections from 15mm to 150mm and flanged connections from 50mm to 300mm, while the lift type foot valve is offered in both screwed and flanged variants ranging from 25mm to 100mm. Valves up to 150mm size feature a single circular door, whereas sizes above 150mm are designed with two semi-circular doors for improved flow balance and operational efficiency.
Designed for almost full flow rate, the Single Door Foot Valve ensures minimal pressure loss and smooth suction performance. The valve undergoes rigorous hydraulic testing, with a body test pressure of 1.5 MPa and a seat test pressure of 1.0 MPa, ensuring high strength and leak-proof operation.
The K-518 Single Disc Design is suitable for standard plumbing and pumping applications, while the K-519 Double Disc Design is ideal for larger pipeline sizes requiring enhanced stability and flow control.
In conclusion, the Single Door Foot Valve is a dependable and efficient solution for plumbing systems, offering excellent backflow prevention, robust construction, and compliance with industry standards, making it a preferred choice for engineers, plumbers, and contractors.
