Z41T004 OS&Y Metal Seated Gate Valve PN10 BS5163
Z41T004 is a DN10 to DN2600 OS&Y metal seated gate valve rated PN10, designed for on-off service in water, power, petrochemical, heating, marine, pharmaceutical and metallurgical pipelines. It operates via a multi-turn handwheel, cap or gearbox and is built to the BS5163 flange standard. The valve features a metal seat for high-temperature and high-pressure service, with a rising stem that indicates the valve position during operation.

What This Model Gives You
- Multi-turn operation allows precise control and clear position indication via the rising stem
- Metal seat provides durability and sealing integrity in high-temperature and high-pressure applications
- Built to BS5163 flange standard for compatibility with international piping systems
- Rising stem design gives visual confirmation of open or closed position
- Available across the full nominal diameter range from DN10 to DN2600
- Part of a valve programme certified to ISO 9001 and ISO 14001
Problems It Removes
- Lack of visual position indication in quarter-turn valves leads to uncertainty during operation
- Rubber seats fail under high temperature or abrasive media; metal seats offer longer life
- Inconsistent flange standards cause installation delays; BS5163 ensures compatibility
- Small-diameter gate valves are often unavailable in standard ranges; this model covers DN10 to DN2600
- Mixed valve types on a project increase spare parts inventory; a single series simplifies stock
Where It Is Installed
- Isolation of water supply lines in municipal and industrial distribution systems
- On-off control in low- and medium-pressure steam and hot water heating circuits
- Service isolation in petrochemical and chemical process piping at PN10
- Valve operation in power plant auxiliary systems where visual position indication is required
- Marine and offshore platform piping where metal seats resist wear and corrosion
Buyers It Suits
- Procurement engineers sourcing metal seated gate valves for water and heating systems
- EPC contractors standardising on OS&Y gate valves with rising stem indication
- Plant maintenance teams needing reliable on-off valves with visible position feedback
- Valve distributors stocking a full range of DN10 to DN2600 gate valves
- Engineering firms specifying BS5163-compliant valves for international projects
How It Is Built
- Multi-turn operation via handwheel, cap or gearbox
- Rising stem with external thread (OS&Y) for position indication
- Metal seat for high-temperature and high-pressure service
- Built to BS5163 flange standard
- Suitable for water, steam, oil, gas and non-corrosive media
- Part of a valve programme covering DN10 to DN2600 and 0.05 to 4.0 MPa
Material Selection
- Body, disc and stem materials are confirmed per order based on the medium and temperature
- Seat material is metal, selected to match the service conditions
- Material certificates are issued with the order upon request
How It Is Made
- Body castings inspected and machined on in-house fine machining equipment
- Disc and stem machined and assembled with the rising stem mechanism
- Metal seat fitted and aligned for full closure and sealing
- Valve assembled and tested under pressure before packing
- Marked, wrapped and crated for container shipment from Tianjin
How It Is Checked
- Dimensional checks on body face-to-face length and flange bolt pattern before assembly
- Seat and shell tightness testing on the assembled valve
- Rising stem travel and full multi-turn operation verified on every unit
- Testing carried out on the 10 sets of imported inspection and testing equipment
- Records maintained under the ISO 9001 quality management system
Certificates Issued With This Valve
- ISO 9001 quality management system certification
- ISO 14001 environmental management system certification
Certification statements are limited to the management system certificates the factory actually holds. Product-level approvals for your market are confirmed before order.
What Can Be Changed
- Seat and body material selected for the medium and temperature on the buyer's line
- Handwheel, cap or gearbox fitted before shipment
- Flange drilling matched to the buyer's piping standard
- Private label marking and packing on OEM orders
- Mixed-diameter orders combined with other valves in one container
How It Compares With the Alternatives
| Resilient seated gate valve | The metal seat withstands higher temperatures and pressures but requires more torque to operate |
|---|---|
| Quarter-turn butterfly valve | The gate valve offers a full bore and better throttling control but requires more space and turns more times to open |
| Lug type gate valve | The OS&Y design provides visual position indication; the lug type does not |
| Butterfly valve at DN100 | The gate valve provides a full unobstructed bore and better sealing at higher pressure, but is heavier and slower to operate |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on both pipe flanges before ordering
- Ensure the stem is fully closed before installing the valve into the pipeline
- Turn the handwheel slowly and evenly to avoid stem binding or seat damage
- Do not use the valve for throttling; it is designed for on-off service only
- Inspect the stem packing regularly and replace if leakage is detected
- Cycle the valve periodically on lines that remain in one position for long periods

Z41T004 OS&Y Metal Seated Gate Valve PN10 BS5163 FAQ
What size and pressure rating is Z41T004?
It is a gate valve with nominal diameter from DN10 to DN2600 and pressure rating PN10. The exact size and flange standard are confirmed on request based on your piping system.
Is this valve quarter-turn?
No. Z41T004 is a multi-turn gate valve operated by handwheel, cap or gearbox. It is not a quarter-turn valve.
Which materials are used for the body, disc and seat?
Material selection depends on the medium and temperature on your line. We confirm the combination with the quotation and issue material certificates with the order on request.
Can it be supplied with a gearbox instead of a handwheel?
Yes. The valve can be fitted with a gearbox before shipment. The stem accepts a gearbox for easier operation in larger sizes.
Do you supply the larger diameters in the same series?
Yes. The Z41T004 series continues through the full nominal diameter range from DN10 to DN2600.
What certification does the factory hold?
Tianjin MIC Valve Co., Ltd. is certified to the ISO 9001 quality management system and the ISO 14001 environmental management system.
