Industrial Applications
Why Choose BallValve Technology’s Stainless Steel Flanged Y-Strainers?
1) CE (2014/68/EU), UKCA, API, ASME, ISO 9001 certified. Full compliance with global pressure equipment and quality management standards – no regional restrictions, no documentation gaps.
2) ATEX certified for explosive atmospheres. This strainer is compatible with ATEX Zone 1&21 and Zone 2&22, making it suitable for use in hazardous environments where explosive atmospheres may be present – a critical requirement for chemical and petrochemical facilities.
3) Stainless steel EN 1.4408 construction for superior corrosion resistance. The body, bonnet, and draining cap are constructed from high-grade stainless steel, providing excellent resistance to corrosion in aggressive chemical and pharmaceutical environments.
4) AISI 316 removable filter for easy maintenance. The removable stainless steel filter allows for easy cleaning or replacement without removing the entire strainer from the pipeline, reducing maintenance downtime.
5) Wide temperature range for demanding applications. Rated from -40°C to +200°C, this strainer is suitable for low temperature applications as well as high temperature processes, with steam capability up to 10 bars.
6) TFM 4215 gaskets for reliable sealing. The bonnet and cap are sealed with high-performance TFM 4215 gaskets, ensuring leak-tight operation across the full temperature and pressure range.
7) Threaded BSP draining cap for easy blowdown. The draining cap allows for connection of a draining valve, enabling easy removal of collected debris without disassembling the strainer.
8) Ten years of field wear data back every design margin. When you order a strainer, you receive an anonymized summary of identical or similar service duty (fluid, temperature, cycle frequency) from our field archives, including observed screen wear patterns, blowdown intervals, and maintenance recommendations.
9) Documentation is not an extra – it’s a serial number’s companion. Enter your strainer’s serial number on our portal: you get EN 10204 3.1 mill certificates, NDE reports, material verification, and the original assembly log. No separate request form, no waiting.
10) Performance witness test is your right, not a premium. Any strainer order includes one free witness test (your inspector or a third party) at our facility, with a 48‑hour notice. Witness includes hydrostatic shell test, leakage test, and screen integrity verification. No “witness fee”, no minimum quantity.
Frequently Asked Questions
Cleaning frequency depends on media cleanliness, mesh size, and flow rate. Monitor pressure drop — clean when it increases by 50% from the clean reading (or exceeds 0.5–0.7 bar). Clean gas lines may need annual cleaning; dirty water may need weekly.
Screen lifespan (typically 1–5 years) is affected by abrasion, corrosion, and physical damage during cleaning. Keep a spare screen to minimize downtime.
Yes. Our Y-Strainers are designed per ASME B16.34 and tested per API 598. Cast iron bodies comply with ASME B16.1. End connections follow ASME B16.5, B16.25, or B16.11. Potable water models feature NSF/ANSI 61 & 372 certification. Material test certificates (EN 10204 3.1/3.2) are available upon request.
Y-Strainers are passive devices and do not have actuator mounting interfaces for standard operation. For automated blowdown, we can supply a mounting pad for a ball valve actuator on the blowdown port — this is a custom option. Please contact us for specific requirements.
Y-Strainers don’t have “full-port” designs like ball valves. Flow restriction depends on:
-
Screen open area ratio (OAR): Typically 2:1 to 3:1 for Y-Strainers.
-
Mesh size: Finer mesh increases pressure drop.
Higher OAR = lower pressure drop and longer cleaning intervals. For critical low-pressure-drop applications, consider a larger strainer or basket strainer.
Yes, with correct material selection:
-
Steam: WCB with graphite seals handles up to 425°C; chrome-moly for higher temperatures.
-
Air: Carbon steel is typically sufficient.
-
Acid: Requires 316SS (CF8M), alloys (Hastelloy, MONEL), or PTFE-lined bodies. Screen material must match the acid type.
Always verify the pressure-temperature rating for your specific media.
-
Installation: Install with screen pointing downward in horizontal lines. Match flow arrow direction. Do not overtighten bolts.
-
Maintenance: Depressurize before opening cover. Replace gasket if damaged. After reassembly, perform a low-pressure leak test.
-
Torque: Use a calibrated wrench and star pattern. Typical torque: 50–150 N·m depending on bolt size.
The choice depends on the size of particles you need to capture. As a general guideline:
-
10–20 Mesh (≈841–2000 µm): For coarse straining, such as removing weld slag, rust, or large debris from new pipelines.
-
40–60 Mesh (≈250–400 µm): For general protection of pumps, control valves, and meters.
-
80–100 Mesh (≈149–177 µm): For fine straining, such as protecting spray nozzles or steam traps.
-
Perforated plates (1/32″–1/4″): Used when strength is more important than fine filtration.
If you’re unsure, we recommend starting with a 20–40 mesh for most liquid applications. We also offer custom mesh sizes upon request.
Our Y-Strainers are available in sizes from ½” (DN15) to 24″ (DN600), with pressure ratings ranging from Class 125 to Class 2500 (PN10 to PN420). The specific rating depends on the body material and connection type. For example, cast iron bodies typically follow Class 125/250 per ASME B16.1, while steel bodies follow Class 150/300/600 per ASME B16.5 and B16.34. Please refer to our product datasheets for detailed specifications by model.
| Stage | Procedure | Description |
|---|---|---|
| Before Production | PMI (Positive Material Identification) test | Raw material verification |
| In-Production | Dimensional checks | At critical machining stages |
| Post-Production | High-pressure hydrostatic shell test (1.5× rated pressure) Low-pressure air seat test (0.6 MPa) to verify shut-off Optional tests: helium leak test (ISO 15848), fire-safe test, or cryogenic test | Final assembly testing |

All test records are archived for a minimum of 10 years and can be provided with each shipment. Or you can specify any third-party test institutions.
Our manufacturing facility is certified to ISO 9001:2015 for design, production, and after-sales service of industrial valves. Additionally, we hold ISO 14001:2015 (environmental management) and ISO 45001:2018 (occupational health and safety). All our ball valves for the European market comply with PED 2014/68/EU, and we can supply valves with ATEX certification for explosive atmospheres upon request. Our quality system is audited annually by third-party notified bodies.
Absolutely. For standard ball valves, we can offer off-the-shelf samples of common sizes (1/2″ to 4″) at a discounted price, with a refundable deposit that can be credited toward a future bulk order. For custom or larger sizes, we accept small trial orders (as few as 2–5 pieces) after a non-recurring engineering (NRE) fee is agreed. The NRE fee will be waived once the customer proceeds to a production order of 50 pieces or more.
We offer flexible payment terms based on order value and customer history. For standard orders: 30% deposit by T/T (wire transfer) with 70% balance before shipping. For larger or repeat customers, we can consider 20% deposit + 80% balance payment.
- For standard models, the minimum order quantity (MOQ) is usually 100 pieces per size. For sizes that are in stock, it takes 3 to 5 business days to ship after you place your order. Our usual lead time for making standard catalog valves that aren’t in stock is 15 to 25 business days after we get your order and approve the drawing.
- Custom models (with special materials, pressure classes, actuator mounting, custom logos, etc.): The minimum order quantity (MOQ) varies, so please get in touch with our sales team for a full quote. The lead time is usually 15 to 45 days, depending on how complicated the process is. Also, we offer a mixed-model consolidation service for distributors to help them deal with their inventory problems.
