Product Overview
What Is A Y Strainer Ball Valve?
A ball valve with integrated Y strainer - also referred to as a female Y strainer ball valve or strainer ball valve combination - merges two pipeline components into one compact unit:
- A quarter-turn full-bore ball valve for reliable on/off shut-off
- An inline Y-type strainer to filter particulate matter before it reaches downstream equipment such as pumps, meters, and control valves
The result is a more compact installation with fewer threaded joints, reduced total cost of components, and simplified maintenance access - all in a single stainless steel body that meets API 608 and API 598 test standards.

Design Features
Full Bore Design
The bore matches nominal pipe diameter - no flow restriction, no pressure drop penalty, piggable where required. Critical for applications where system efficiency directly affects operating cost.
Ball Valve with Integrated Strainer - One SKU, Two Functions
Replaces a separate strainer + ball valve assembly. Fewer connections mean fewer potential leak paths - relevant for procurement teams managing system integrity and maintenance intervals.
In-Service Packing Adjustment
Stem packing can be tightened without removing the valve from line. Reduces shutdown time and labor cost during routine maintenance.
Back Seat / Multiple Leakage-Proof Design
Secondary back seal provides an additional containment barrier and allows packing inspection under pressure, meeting safety requirements in oil & gas and chemical environments.
Anti-Blowout Stem
Stem ejection prevention design is standard - not an optional upgrade. Complies with API 608 safety requirements for pressurized service.
Resilient Seat Sea
Spring-loaded PTFE seats maintain constant contact with the ball under thermal cycling and pressure fluctuation, ensuring bubble-tight shutoff throughout service life.
Investment Cast Body
Precision lost-wax casting produces consistent grain structure and superior surface finish. Tighter dimensional tolerances reduce the QC rejection rate at incoming inspection for your assembly line.
Edge-Packed Filter Screen
The stainless steel mesh is edge-packed to prevent particulate bypass at the screen perimeter - a common failure point in lower-grade strainer designs.

Frequently Asked Questions
Q: What is the difference between a Y strainer ball valve and buying a separate strainer and ball valve?
A: A ball valve with integrated strainer reduces your component count, eliminates one set of threaded connections, lowers installation labor, and simplifies future maintenance access - all from a single SKU. For distributors, it also simplifies catalog management and reduces stocking SKUs compared to maintaining separate strainer and valve inventories.
Q: Is this a stainless steel Y strainer ball valve? What grade is available?
A: Yes. The body and bonnet are precision investment-cast in CF8 (equivalent to ASTM A351 Grade CF8, comparable to SS304) or CF8M (equivalent to SS316). Ball and stem are forged F304 or F316. Full material traceability with mill test reports is available for project orders.
Q: What mesh sizes are available, and can we specify mesh for a bulk order?
A: Standard options are 40, 80, and 100 mesh SS304/SS316 stainless steel screens with edge-packed construction. Yes - mesh grade can be fixed per SKU for bulk supply agreements. Mixed mesh configurations within a single order are also accepted.
Q: Which thread standards does LEADTEK support?
A: NPT (ASME B1.20.1), BSPT (BS 21 / DIN 2999), BSPP (BS EN 10226 / ISO 228-1), JIS B 0203, and ISO 7-1. Thread type is confirmed at order stage. Custom thread forms available for OEM orders.
Q: What is the MOQ for a standard stainless steel Y strainer ball valve?
A: MOQ starts from 100 pcs per size/spec combination for standard configurations. For sample evaluation, we offer free samples for qualified buyers. Contact our sales team with your project or distribution requirements.
Q: Can LEADTEK supply with OEM markings or private label?
A: Yes. We offer laser-engraved custom logo, part numbers, and pressure ratings on the valve body. Custom packaging (carton, poly bag, labels) is also available. Please provide your branding requirements when submitting your RFQ.
Q: What certifications and test documentation can you provide?
A: Standard shipments include pressure test certificates. On request: mill test reports (MTRs), RoHS compliance declaration, ISO 9001 certificate copy, and third-party inspection coordination (SGS, BV, TÜV) for project orders.
Q: What is the delivery lead time for bulk orders?
A: Standard sizes (½"–2" in SS304, standard thread) ship within 7 business days ex-works for in-stock configurations. Custom specifications (non-standard thread, SS316 screen, OEM markings) require 15–25 business days. Contact us early for project scheduling.
Q: Is the strainer screen serviceable in the field without removing the valve?
A: Yes. The strainer bonnet cap (Part 16) is removable for screen cleaning or replacement without disturbing the valve body or pipeline connections - an important maintenance advantage for end-user clients in your distribution network.
Q: What temperature and pressure limits apply to this valve?
A: With standard PTFE seats: -40°C to 120°C at rated 1,000 PSI. Upgrading to PTFE+20% carbon fiber seats extends the temperature rating to 200°C. Operating conditions outside these ranges should be discussed with our engineering team before ordering.
