What types of valves does KR Valve manufacture?

KR Valve manufactures more than 500 valve products, including wafer, lug, concentric and double eccentric butterfly valves, resilient seat, metal seat and knife gate valves, dual disc, swing, lift and ball type check valves, ball valves, hydraulic water control valves such as 200X pressure reducing valves and 100X remote float valves, and Y type strainers.

Which international standards do KR valves follow?

Our range covers common international standards such as DIN F5 face-to-face gate valves, BS5163 resilient seat gate valves, BS5153 dual disc check valves, ANSI flanged strainers and PN16 pressure rated water control valves. Non-standard designs can be engineered to your drawings.

Do you offer OEM valve manufacturing?

Yes. In addition to our own KR brand, we provide OEM services, including customer branding, specified body and seat materials, actuation options and project-specific packaging.

Should I choose a wafer or a lug butterfly valve?

Wafer butterfly valves are lighter and more economical and are clamped between two flanges, making them ideal for standard water and HVAC lines. Lug butterfly valves have threaded lugs that allow dead-end service and removal of downstream piping without draining the whole line, which suits maintenance-critical systems.

How is valve quality controlled before shipment?

Every process is inspected from raw material to finished product, and 100% of finished valves are inspected before dispatch. Production plans and lead times are defined upfront through full-chain supply control.

Product Description

Product Specifications

Valve Type: Flange Y type strainer

Structure: Removable

Standard: BS5155

Workmanship: Investment casting

Sealing direction: Single-directional

Sealing grade: Zero leakage

Temperature: -20°C < T < 120°C

Operation: Automatic

Characteristics

The fluid enters from the inlet end of the filter and flows through the flanged y strainer. Here, the fluid must pass through a filter to flow out from the outlet end. Solid impurities in fluids, such as rust, sediment, pipeline debris, scale, etc., are intercepted on the inner wall or bottom of the filter due to their particle size being larger than the filter aperture. The clean fluid flows out through the filter and enters downstream equipment.

Ductile iron GGG40 Y type strainer with SS304 filter

Advantages

1. Compact structure

Small space occupation. The Y-shaped design allows it to adapt well to straight pipe sections, especially suitable for installation positions with limited space.

2. Low pressure drop

Strong flow capacity. In a clean state, the flow channel is smooth and has little impact on system pressure loss.

3. Easy maintenance

Easy and fast maintenance. Most designs allow online maintenance. Simply close inlet/outlet valves, open cover, remove filter screen to clean or replace.

Application Scenarios

The cast iron strainer widely used in municipal water supply, installed in front of the building's inlet main pipeline and irrigation system, filters sediment.

Frequently Asked Questions (FAQ)

What is the main function of a Flanged Y-Type Strainer?

It mechanically removes solid impurities such as rust, sediment, and pipeline debris from flowing fluids, protecting downstream equipment (pumps, meters, valves) from damage and blockage.

What design standard does this strainer comply with?

This Flange Y type strainer is manufactured according to the BS5155 standard, utilizing investment casting for precise structural integrity and zero leakage sealing performance.

What operating temperature range can this valve handle?

The strainer operates reliably within a working temperature range of -20°C < T < 120°C, making it suitable for municipal water supply and standard industrial fluid systems.

How do you clean and maintain the strainer screen?

Maintenance is simple and fast. Close the isolation valves, open the removable cover, remove the stainless steel screen for flushing or replacement, and re-install without disassembling the main pipe body.

Where is this Y-type strainer typically installed?

It is widely installed at the main inlet pipelines of buildings, municipal water supply networks, and agricultural irrigation systems in front of key pressure control or measuring equipment.
