Z45X050 NRS Resilient Seated Gate Valve DN350 Bevel Gear
Z45X050 is a DN350 resilient seated gate valve with a bevel gear operator, designed for on-off service in water, low-pressure industrial, and heating systems. It operates via multi-turn handwheel, cap or gearbox action, providing a full bore flow path with a tight seal. The resilient seat ensures bidirectional shut-off and minimizes wear during operation.

What This Model Gives You
- Full bore flow path maintains unobstructed pipeline capacity with minimal pressure drop
- Resilient seat provides reliable bidirectional sealing without requiring precise alignment
- Multi-turn bevel gear operator allows precise control and high torque transmission for large valves
- Robust construction suitable for repeated operation in water and low-pressure service lines
- Part of a valve programme covering DN10 to DN2600 and 0.05 to 4.0 MPa, enabling consistent sizing across projects
Problems It Removes
- Gate valves with metal seats wear quickly in water service due to particle abrasion; the resilient seat reduces wear and extends service life
- Lack of consistent sizing across valve families forces buyers to manage multiple SKUs; this model is part of a unified DN10 to DN2600 range
- Multi-turn operation is required for large valves where quarter-turn mechanisms lack torque; the bevel gear provides sufficient mechanical advantage
- Existing DN350 systems need reliable isolation valves that do not restrict flow; the full bore design maintains pipeline capacity
- Buyers need a valve that can be operated manually or with a gearbox without changing the body design
Where It Is Installed
- Isolation of large-diameter water supply lines in municipal distribution networks
- On-off control in low-pressure heating circuits where full bore flow is required
- Service line shut-off in power plant auxiliary systems with DN350 piping
- Process isolation in chemical and pharmaceutical plants using water-based media
- Maintenance isolation in sewage treatment plant pipelines with DN350 connections
Buyers It Suits
- Water utility engineers sourcing large-diameter isolation valves for municipal networks
- HVAC and heating system designers needing full bore shut-off in district heating loops
- Plant maintenance teams replacing gate valves in existing DN350 piping systems
- EPC contractors standardizing on a single valve type across multiple project phases
- Valve distributors stocking resilient seated gate valves from DN10 to DN2600
How It Is Built
- Multi-turn operation via handwheel, cap or bevel gear operator
- Resilient seated disc with full bore flow path
- Body and disc materials confirmed per order against the operating medium and temperature
- Bevel gear operator provides mechanical advantage for large valve actuation
- Part of the Z45X series of resilient seated gate valves extending from DN10 to DN2600
Material Selection
- Body, disc and seat materials are confirmed per order based on the medium and temperature
- Seat material is selected from the resilient variants offered across the Z45X series
- Material certificates are issued with the order when requested by the buyer
How It Is Made
- Body casting inspected and machined on in-house fine machining equipment
- Disc and seat assembled with precise alignment to ensure even contact
- Bevel gear operator fitted and tested for smooth multi-turn operation
- Valve assembled and pressure tested before packing
- Marked, wrapped and crated for container shipment from Tianjin
How It Is Checked
- Dimensional check of flange bolt pattern and face-to-face length before assembly
- Seat tightness and shell integrity tested on the assembled valve
- Multi-turn operation verified for full travel and smooth gear engagement
- Testing conducted 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 disc variant selected for the medium and temperature on the buyer's line
- Flange drilling matched to the standard used on the buyer's pipework
- Bevel gear operator fitted with handwheel or cap as specified
- Private label marking and packaging available on OEM orders
- Mixed-diameter orders combined with other valves in one container
How It Compares With the Alternatives
| DN350 wafer butterfly valve | The butterfly valve has shorter face-to-face length but may not provide full bore flow; the gate valve maintains full bore and lower pressure drop |
|---|---|
| DN350 metal seated gate valve | The metal seated valve handles higher temperature and pressure but requires more torque and wears faster in water service; the resilient seat reduces wear and sealing force |
| DN350 quarter-turn ball valve | The ball valve operates faster but has a reduced bore and higher cost; the gate valve offers full bore and lower cost for water service |
| DN350 lug type butterfly valve | The lug body allows end-of-line service; the gate valve requires flanges on both sides and cannot be used as a dead-end closure |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on both pipe flanges before ordering
- Ensure the bevel gear operator is accessible for operation and maintenance
- Do not force the valve open or closed; use the gear to apply steady torque
- Cycle the valve periodically on lines that remain in one position for long periods
- Do not use the valve as a throttling device; it is designed for on-off service only
- Inspect the seat and disc after long periods of inactivity before operation

What is the pressure rating and flange standard for Z45X050?
The pressure rating and flange standard are confirmed against your line data when we quote, as the same body is offered in multiple variants.
Can this valve be used at the end of a pipe run?
No. A resilient seated gate valve requires flanges on both sides to seal. For end-of-line service, use a different valve type with a blind end or lug body.
Which materials are used for the body, disc and seat?
Material selection depends on the medium and temperature on your line, so we confirm the combination with the quotation and issue material certificates with the order on request.
Can it be supplied with a different operator instead of the bevel gear?
Yes. The valve can be supplied with a handwheel, cap, or bevel gear. The operator type is selected during the quotation process.
Do you supply the larger diameters in the same series?
Yes. The Z45X resilient seated gate valve series continues through the larger nominal diameters, and our valve programme covers DN10 to DN2600 across all families.
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.
