KR Valve Expands Product Range for Water Treatment Systems

India - 2nd August 2026 - KR Valve (Tianjin) Co., Ltd., a company with over 20 years of experience in manufacturing valves, has expanded its product range to include a wide selection of over 500 valve products, including butterfly, gate, check, and water control valves, as well as Y strainers. The company's portfolio has been exported to over 50 countries and regions, underscoring its global reach and commitment to quality.

KR Valve operates in various industries such as water treatment, dam construction, commercial buildings, energy and heating, and chemical engineering. The company adheres to the ISO-9001 quality management system and boasts over 30 production equipment, ensuring continuous updates and improvements in its manufacturing processes. Its rigorous inspection department guarantees 100% inspection quality of all products, maintaining high standards in every aspect of production.

The company offers a comprehensive RFQ Checklist for engineers and procurement teams, detailing the selection and installation of valves in water treatment systems. This checklist includes guidance on different valve types, such as butterfly valves, gate valves, check valves, and hydraulic control valves, along with specific considerations for each type.

For butterfly valves, KR Valve advises on the suitability of the disc, seat, connection, and actuator for the intended duty. The company highlights the advantages of hydraulic butterfly valves and differentiates between midline and eccentric butterfly valves. It also compares concentric and double offset butterfly valves, recommending the double offset butterfly valve for steam applications. Additionally, KR Valve distinguishes between wafer and lug butterfly valves, noting that the lug type can be used for dead-end installations.

In the context of gate valves, the company emphasizes the importance of on/off isolation in compatible water services. KR Valve provides guidance on selecting resilient seated gate valves, differentiating between rising stem and non-rising stem gate valves. The company also offers insights into the applicable environments for EPDM gate valves and the differences between wedge and resilient gate valves.

Check valves, designed to prevent reverse flow, are another focus area. KR Valve explains the differences between dual disc, swing, and lift check valves, and advises on their appropriate installation, especially at pump outlets. The company also addresses the safe installation of check valves on pump suction sides.

Hydraulic control valves, which manage pressure or level control, are discussed in detail. KR Valve outlines the selection process, including the pilot system's control variable and operating range. The company also provides guidance on the use of hydraulic control butterfly valves instead of electric ones, and explains how hydraulic slow-closing butterfly valves can eliminate water hammer.

Y strainers, used to capture specified debris, are another key component. KR Valve advises on selecting the appropriate screen opening and pressure loss, and differentiates between Y strainers and basket strainers. The company also provides recommendations for installing Y strainers before control valves or pumps, and discusses the importance of cleaning the screen.

KR Valve's RFQ Checklist serves as a practical tool for engineers and procurement teams, ensuring that each installation point is correctly connected to the defined function. The checklist covers service, hydraulics, installation, construction, operation, and acceptance requirements, helping to streamline the quotation process and reduce the risk of technically incomplete descriptions reaching the purchasing stage.

By providing detailed guidance on valve selection and installation, KR Valve aims to support the efficient and effective management of water treatment systems, ensuring that engineers and procurement teams can make informed decisions.
