SS 316 Ball Valves

SS 316 Globe Valves

SS 316 Check Valves

SS 316 Needle Valves

SS 316 Butterfly Valves

SS 304 Ball Valves: Delivers quick quarter-turn operation and bubble-tight shutoff; ideal for general liquid and gas isolation in processing plants.
SS 304 Globe Valves: Designed for accurate flow throttling and reliable performance in high-pressure steam and water circuits.
SS 304 Check Valves: Automatically prevents reverse flow, protecting upstream equipment like pumps and compressors from process backflow.
SS 304 Needle Valves: Features a fine-threaded stem for precise micro-flow regulation and fluid metering in instrument manifolds and testing setups.
SS 304 Butterfly Valves: Provides a compact, space-saving design with low pressure drop for flow control in large-diameter piping systems.

Pressure-Temperature Performance Parameters

Designed to ASME B16.34 standards, our Grade 304 valve bodies manage thermal stresses and pressure drops. Below are the maximum working pressure capabilities across operational temperatures:

Pressure Class	Max Working Pressure at 38°C (100°F)	Max Working Pressure at 200°C (392°F)	Max Working Pressure at 400°C (752°F)
Class 150#	275 PSI (19.0 Bar)	200 PSI (13.8 Bar)	140 PSI (9.7 Bar)
Class 300#	720 PSI (49.6 Bar)	600 PSI (41.4 Bar)	490 PSI (33.8 Bar)
Class 800# (Forged)	1920 PSI (132.4 Bar)	1600 PSI (110.3 Bar)	1300 PSI (89.6 Bar)
Class 1500#	3600 PSI (248.2 Bar)	3000 PSI (206.8 Bar)	2450 PSI (168.9 Bar)

Key Advantages of SS 304 Valves

Atmospheric & Organic Acid Resistance: 18% chromium content forms an instant passive oxide layer that prevents surface oxidation and rusting in potable water and organic fluid lines.
Cryogenic Impact Toughness: The non-magnetic austenitic matrix maintains excellent mechanical notch toughness at temperatures as low as -196°C without brittle failure.
Zero-Leakage Sealing Performance: Precision CNC-machined disc and seat surfaces combined with high-grade PTFE or flexible graphite packing guarantee zero-leakage compliance under API 598 protocols.
Smooth Internal Flow Path: Clean investment cast (CF8) and forged (F304) internal passages prevent media accumulation and minimize pressure drop across the body cavity.
High Weldability & Fabrication Integrity: Low susceptibility to thermal cracking allows easy inline welding of socket weld and butt weld end configurations without pre-heat treatment.

Key Industrial Applications

Food, Beverage & Sanitary Processing: Hygienic flow control in dairy product pipelines, brewery lines, and CIP (Clean-in-Place) fluid systems.
Municipal Water Treatment & Desalination: High-pressure feed control, pump isolation, and filtration manifold loops.
Chemical & Organic Solvent Handling: Conveyance of nitric acid solutions, organic solvents, and industrial process wastewater.
Power Generation & Steam Utilities: Auxiliary boiler feedwater isolation, condensate recovery lines, and cooling tower piping.
Pulp, Paper & Textile Lines: Starch liquor control, general utility steam lines, and dye-house fluid isolation.
