Product Description

Product Description

forede® presents the Z45X Flange End Non-Rising Stem (NRS) Gate Valve, a high-performance solution tailored for dependable flow control and shut-off in demanding piping environments.
 
This valve's non-rising stem design is a standout, enabling operation in spaces with limited vertical room-a major benefit for retrofitting or compact installations. The stem is made of 2CR13 Stainless Steel, ensuring long-term resistance to corrosion and mechanical stress. Both the bonnet and body utilize Ductile Iron QT450, providing exceptional durability even under frequent pressure fluctuations. The seal, featuring Ductile Iron QT450 covered by NBR, guarantees a tight seal to prevent leakage, while the flange end meets ANSI150LB, GB Standard, and BS Standard for broad compatibility. Its epoxy red or blue surface finishing offers robust corrosion protection and visual distinction.
 
Models range from 2 Inch (50 mm) to 14 Inch (350 mm), all with flange end connections, NRS valve type, and a working pressure of 1.0/1.6 Mpa, available in Red or Blue.
 
Suitable for municipal water supply, industrial fluid handling, and sewage systems, the Z45X Flange End NRS Gate Valve is engineered by forede® to deliver consistent, long-lasting performance. It's an excellent choice for those prioritizing reliability and space efficiency in flow control applications.

FAQ

1. Advantage of Non-Rising Stem (NRS) Design

Q: What's the benefit of the NRS (Non-Rising Stem) design in this gate valve?
A: The NRS design means the stem doesn't rise when opening/closing, saving vertical space. It's ideal for tight spaces like underground pipelines, where vertical clearance is limited.

2. NBR Seal Media Compatibility

Q: What fluids should be avoided with the NBR-coated ductile iron seal?
A: NBR (Nitrile Butadiene Rubber) works well with water, oil, and general industrial fluids. Avoid strong acids, alkalis, ketones, or esters-these can damage NBR and cause leaks. For such media, use a valve with FKM seals.

3. Installation Flow Direction

Q: Does this gate valve have a required flow direction during installation?
A: Gate valves are bi-directional (seal both ways). But install according to the "flow arrow" or common fluid direction for even gate stress. This ensures longer seal life and smooth operation.

4. Maintenance Frequency and Key Checks

Q: How often should this valve be maintained, and what parts need attention?
A: Maintain every 3-6 months. Focus on: lubricating the 2CR13 stainless steel stem (use grease), inspecting the NBR seal for cracks/wear, checking flange connections for leaks, and ensuring the handwheel turns smoothly.

5. Sizing for Piping

Q: How to choose the right valve size (e.g., 2 inch vs. 14 inch)?
A: Match the valve size to your pipe's nominal diameter (DN). For a DN50 pipe, choose Z45X-16Q-50 (2 inch); for DN350, choose Z45X-16Q-350 (14 inch). This ensures proper flow and no installation issues.

6. 2CR13 Stem Corrosion Protection

Q: How to protect the 2CR13 stainless steel stem in humid environments?
A: 2CR13 resists rust well, but in humid or coastal areas, clean the stem regularly and apply a stainless-steel protectant. This prevents corrosion and ensures smooth operation.

7. Handwheel Operation Torque

Q: Is the handwheel hard to turn, and does torque change with valve size?
A: Torque increases with valve size-larger valves (e.g., 14 inch) need more force than smaller ones (e.g., 2 inch). If turning is stiff, check for stem corrosion or insufficient lubrication.

8. Epoxy Coating Durability Outdoors

Q: How long does the epoxy red/blue coating last in outdoor conditions?
A: In typical outdoor environments, the epoxy coating lasts 5-8 years. Inspect yearly for chipping; touch up with matching epoxy paint if damaged.

9. Working Pressure Selection

Q: When to use 1.0MPa vs. 1.6MPa working pressure?
A: Choose 1.0MPa for low-pressure systems and 1.6MPa for higher-pressure applications. Never let your system's pressure exceed the valve's working pressure to avoid damage.

10. NRS Gate Valve vs. Rising Stem Gate Valve

Q: When is this NRS gate valve better than a rising stem gate valve?
A: NRS gate valves save vertical space (ideal for underground/limited clearance areas). Rising stem valves let you see the stem position to judge open/closed status. Use NRS when space is tight; rising stem when visual status is needed.
