Engineering Advantages That Drive Performance

Ultra-Low Opening Pressure

Our precision-engineered disc and spring assembly achieves opening pressures as low as 0.002 MPa (2 kPa/0.3 PSI), enabling sensitive flow detection and immediate backflow prevention. Standard configurations operate at 0.02-0.05 MPa (3-7 PSI), customizable to specific system requirements for optimal pump protection.

Rapid Closure & Water Hammer Suppression

Optimized disc geometry and spring-assisted closure mechanism achieve sub-0.1 second response times, reducing water hammer peak pressures by 20-40%. This protects downstream equipment and extends pipeline service life by minimizing fatigue stress cycles in high-frequency applications.

Versatile Design Configurations

Five structural variants - lift, swing, dual-plate, ball, and diaphragm types - accommodate diverse installation constraints and flow conditions. Wafer, threaded, welded, and flanged connections support pressures from vacuum to PN 420/Class 2500 (42 MPa/6090 PSI) across temperature ranges of -196°C to +650°C (-321°F to +1202°F).

Dual Sealing Technology

Interchangeable soft sealing (NBR, EPDM, PTFE) and hard sealing (Stellite, tungsten carbide) options meet FCI 70-2 Class I-VI leakage standards. Hard sealing variants achieve Class VI bubble-tight performance for critical applications requiring zero-leakage over extended service cycles.

Lightweight & Compact Design

Wafer-type construction reduces weight by 70% compared to conventional swing check valves, with face-to-face lengths 40-70% shorter. This space-efficient design facilitates retrofit installations and reduces structural support requirements while maintaining full flow capacity.

Zero Energy Operation

Pressure-differential actuated operation requires no external power or control signals, ensuring fail-safe protection during power outages. Maintenance-free design with wear-resistant springs and sealing surfaces delivers 100,000+ reliable cycles, significantly reducing lifecycle operating costs.

Discover how these engineering advantages can improve your system reliability.

FAQ (Technical & Purchasing) FAQ (Technical & Purchasing)

Frequently Asked Questions

Technical and commercial questions commonly asked by process engineers and procurement teams.

Technical Questions

What are the available pressure ratings and temperature ranges for check valves?

Our check valves cover pressure ratings from vacuum to PN 420 / Class 2500 (42 MPa / 6090 PSI), with temperature capabilities spanning -196°C to +650°C (-321°F to 1202°F). Special alloy configurations extend temperature capability to 800°C (1472°F) for extreme service conditions. Opening pressure differential ranges from standard 0.02-0.05 MPa (2.9-7.3 PSI) to ultra-low 0.002 MPa (0.3 PSI) or high-differential 0.35 MPa (51 PSI) based on application requirements.

How do I select between swing check, lift check, and dual-plate designs?

Design selection depends on flow characteristics, pressure drop tolerance, and installation orientation. Swing check valves offer lowest pressure drop for horizontal pipelines but require adequate clearance for disc swing. Lift check valves provide reliable vertical installation capability with guided disc movement but higher pressure loss. Dual-plate butterfly designs minimize weight and face-to-face dimensions while maintaining bi-directional seating capability, ideal for space-constrained applications.

What sealing technologies are available and how do they affect leakage performance?

Soft sealing options include NBR, EPDM, and PTFE for temperature ranges up to 200°C (392°F), achieving FCI 70-2 Class IV-VI leakage performance. Metal sealing surfaces utilize Stellite or tungsten carbide for high-temperature service above 400°C (752°F), providing Class V performance with superior durability. Replaceable seat designs enable field maintenance and seal upgrade without complete valve replacement, reducing lifecycle costs.

How effective are check valves in preventing water hammer and system damage?

Properly positioned check valves reduce water hammer peak pressures by 20-40% through rapid closure response, typically within 0.1-0.5 seconds of flow reversal. Spring-assisted designs provide controlled closure timing to minimize pressure surge while ensuring complete sealing. Optimized flow passage geometry and lightweight disc construction further reduce closure slam impact, extending both valve and pipeline system service life significantly.

What materials and construction standards apply to different service environments?

Standard construction follows API 594, API 6D, ISO 15761, and GB/T 12236 specifications. Materials range from ductile iron and carbon steel for general service to 316L stainless steel and exotic alloys for corrosive applications. Seawater desalination service utilizes duplex stainless steel construction with NACE MR0175 compliance for sour service environments. All wetted components undergo material compatibility verification against specific process chemistry requirements.

Commercial Questions

What are typical delivery schedules for standard and customized check valves?

Standard wafer and swing check valves in common materials ship within 5-15 business days from our maintained inventory. Custom designs, exotic alloy construction, or special testing requirements typically require 15-25 days depending on material procurement and engineering validation. Emergency replacement service provides 72-hour delivery for critical applications, while consignment inventory programs eliminate lead times for frequently replaced spare parts in plant maintenance schedules.

What warranty terms and performance guarantees are provided?

Standard warranty coverage spans 18-24 months from shipment date, covering manufacturing defects in materials and workmanship with free replacement including expedited shipping. Performance cycle guarantees extend to hundreds of thousands of operations for standard service conditions. Extended warranty programs and performance bonds are available for critical applications, with lifecycle cost analysis supporting total ownership value optimization over extended service periods.

Do you provide application engineering and technical consultation services?

Comprehensive engineering support includes flow analysis, pressure drop calculations, material selection guidance, and installation orientation recommendations. Our technical team provides written application reports with supporting calculations and CAD drawings for system integration. Remote technical support covers troubleshooting, maintenance procedures, and performance optimization, while training documentation supports plant personnel in proper operation and maintenance practices.

What documentation and certifications accompany each valve shipment?

Complete traceability packages include material test certificates, dimensional inspection reports, hydrostatic test results, and seat leakage verification data. ISO 9001 quality system certification ensures consistent manufacturing processes, while EN 10204 3.2 material certificates provide full traceability to steel mill sources. Third-party inspection services and witness testing can be arranged for project-specific quality assurance requirements and international shipping compliance.

Are quantity discounts and long-term supply agreements available?

Volume pricing structures begin at 10-piece minimum quantities for identical specifications, with progressive discounts for larger orders and multi-year commitments. Project-specific pricing considers total package value including installation accessories and technical support services. Partnership agreements provide priority allocation, dedicated inventory management, and preferred pricing for qualified customers with established purchasing patterns and creditworthiness verification.
