About Creep Relief Valve CR Series

The CR-Series are general purpose self operated pressure relieving upstream pressure control valves suitable for controlling many kind of fluids. These valves open in proportion to the rise in inlet pressure beyond set value. Different soft seating discs are available for various fluids for wide pressure and temperature range up to 175oC. These back pressure regulating valves are also well suited for high & varying differential pressure.

It is widely used in Natural Gas, Pressure Creep Relief Function.

Key Features:

Easy to Maintain :Compact design with minimum number of moving parts. Actuator internals, valve disc & trim parts can be replaced without removing the regulator from pipeline.
Glandless Construction :Where positive zero gland leakage is required, the design scores over conventional solutions such as bellow seal etc.., as the gland itself eliminated and hence there wont be gland leakage. Glandless construction eliminates hysteresis, is in improvement of sensitivity & repeatability of the valve.
Tight Shut off Capability :Special trim design eliminates wear and erosion of seating. Providing excellent tight shut off capability over long working life.
Throttling type relief :Smooth sensitive throttling action minimizes pressure surge.
Low Pressure Buildup :Required flow achieved with minimum pressure buildup.
Reset :Better resetting capability than conventional relief valve. Relieve excess pressure and gets reset due to proportionate opening.

High Performance and Efficiency

The CR Series Creep Relief Valve delivers swift and precise relief action, curbing unwanted pressure build-up in pneumatic circuits. With its efficient direct acting design and automatic operation, it maximizes operational uptime while minimizing air consumption and maintenance requirements.

Versatile Installation Options

Designed for flexible mounting, this valve supports both inline and manifold configurations. Available in standard port sizes from 1/8" to 1/2" BSP, users can select the ideal model to fit diverse pneumatic layouts in industrial and automation settings.

Durable Build and Compliance

Constructed from corrosion-resistant aluminum alloy and featuring NBR/EPDM seals, the CR Series ensures long service lifeup to 10 million cycles. It is compliant with RoHS and offers CE certification, making it suitable for global deployment and environmentally conscious operations.

FAQs of Creep Relief Valve CR Series:

Q: How does the CR Series Creep Relief Valve eliminate pressure creep in pneumatic circuits?

A: The CR Series uses a direct acting mechanism to swiftly detect and relieve excess pressure that can develop in pneumatic systems, maintaining stable pressure by venting creep before it affects performance or safety.

Q: What mounting options are available for installation of the CR Series valve?

A: This valve can be installed via inline or manifold mounting, allowing flexibility to match your systems design preferences and ensuring optimal integration into various pneumatic circuits.

Q: When should I adjust the set pressure and what is its range?

A: The set pressure should be adjusted during installation or routine maintenance to align with your systems requirements. The adjustable range is from 0.05 to 0.85 MPa, suitable for a wide range of pneumatic applications.

Q: Where is the CR Series valve most commonly used?

A: It is primarily used in industrial automation and pneumatic systems where maintaining steady air pressure is critical, such as manufacturing lines, packaging machinery, and process equipment.

Q: What process should be followed for maintaining the CR Series valve?

A: Regular inspections for leaks, checking seal integrity, and ensuring the air supplied is filtered and lubricated will help maximize performance. Thanks to high-quality materials and design, only minimal routine maintenance is required.

Q: How does the automatic operation of the valve benefit system efficiency?

A: Since the CR Series operates mechanically and automatically, it responds to pressure changes instantly, without needing power or user intervention. This ensures high efficiency, reduces downtime, and minimizes maintenance costs for the pneumatic system.

Q: What are the advantages of using NBR/EPDM seals in the CR Series valve?

A: NBR/EPDM seals offer excellent resistance to compressed air and operating temperatures from 5C to 60C, ensuring reliable performance, leak prevention, and enhanced product longevity in demanding environments.
