Industrial Valve Procurement Guide: A Comprehensive Walkthrough from Selection to Installation
Industrial Valve Procurement Guide: A Comprehensive Walkthrough from Selection to Installation
Procuring industrial valves is a highly specialized task. Adequate preparation before purchasing can effectively prevent selection errors and resource waste. Before contacting a valve manufacturer, we recommend having the following information clearly defined:
1，Operating Conditions: Type of medium (water, steam, oil, corrosive media, etc.), operating temperature range, pressure class, flow rate requirements, and pipe diameter.
2，Service Environment: Indoor or outdoor installation, ambient temperature, vibration exposure, explosion-proof requirements, and anti-corrosion specifications.
3，Control Requirements: Manual, electric, or pneumatic actuation; whether flow regulation is needed; remote control capabilities; and signal types.
4，Project Requirements: Delivery lead time, budget constraints, certification standards, and warranty period.
The technical team at Like Valve can assist you in organizing these parameters and providing professional selection recommendations.
Core Principles of Valve Selection
1. Selecting Valve Types Based on Medium
Different media require specific valve designs:
1，Water & Wastewater Systems: Ball valves, butterfly valves, gate valves.
2，Steam Systems: Globe valves, ball valves.
3，Oil & Petroleum Systems: Ball valves, gate valves.
4，Corrosive Media: PTFE-lined valves, stainless steel ball valves.
5，Media with Suspended Solids/Particles: Knife gate valves, plug valves.
2. Choosing Materials Based on Pressure and Temperature
Valve material directly dictates service life and operational safety:
1，Ambient/Low Temp & Low/Med Pressure (-20℃ to 200℃ / -4℉ to 392℉, PN≤16 / Class 150): Cast iron, carbon steel.
2，Medium Temp & Medium Pressure (200℃ to 400℃ / 392℉ to 752℉, PN≤64 / Class 400-600): Carbon steel, alloy steel.
3，High Temp & High Pressure (>400℃ / >752℉, PN>64 / Class 900+): Alloy steel, stainless steel.
4，Corrosive Media: 304/316 Stainless Steel, Duplex Steel.
3. Matching Connection Types to Pipe Sizes
a, DN15 - DN50 (NPS ½" - 2"): Threaded connections, socket-welded.
b, DN15 - DN300 (NPS ½" - 12"): Flanged connections.
c, DN50 - DN2000 (NPS 2" - 80"): Flanged or wafer-style connections.
d, >DN300 (>NPS 12"): Flanged connections.
Frequently Asked Questions (FAQ)
What technical parameters are required for procuring industrial valves?
Core parameters include medium type, operating temperature, working pressure, pipe diameter, connection type, and actuation method. Any special requirements (e.g., explosion-proof, low leakage) must also be specified. Like Valve provides customizable selection checklists to help you organize these parameters efficiently.
What tests should be conducted after installing an industrial valve?
Post-installation testing should include:
a, Hydrostatic shell test (at 1.5 times the nominal pressure).
b, Seat sealing test (at 1.1 times the nominal pressure).
c, Operational flexibility checks.
Every product leaving Like Valve undergoes rigorous factory testing. However, we strongly recommend conducting on-site re-inspections post-installation to ensure system integrity.
What is the typical delivery lead time for industrial valves?
Standard products generally take 7–15 days. Large-diameter or special-material valves typically require 15–30 days, while custom-engineered solutions may take 30–60 days. Thanks to our robust inventory management, Like Valve offers rapid dispatch for most standard products.
