Meaning of 1000 WOG & Core Differences Between T/L Type Balls
3.1 Detailed Explanation of 1000 WOG
1000 WOG is a universal pressure and media rating in the valve industry:
● W (Water): Suitable for clean water, circulating water, tap water, slightly corrosive wastewater, etc.
● O (Oil): Compatible with mineral oil, hydraulic oil, lubricating oil, diesel, gasoline, etc.
● G (Gas): Suitable for natural gas, LPG, compressed air, inert gas, etc.
● 1000: Rated working pressure 1000 psi (≈6.9 MPa).

Material Selection Guide
● 304 Stainless Steel: For general water, oil, gas; -20°C~180°C; most common applications.
● 316 Stainless Steel: For mildly corrosive media, chloride-containing fluids; better pitting resistance.
● 316L Stainless Steel: For strong corrosive, acid, alkali, chloride gas; excellent weldability & corrosion resistance.
● Seat Matching:
PTFE: good sealing, general temperature.
PPL: high temperature up to 260°C.
Product Definition
Stainless Steel Internal Thread Tee Ball Valves is a multi-port flow control valve with 1000 WOG rating, suitable for Water-Oil-Gas service. It uses T-type or L-type ball to realize flow mixing, diverting or switching by 90° rotation.
With one-piece or 2-piece forged body and female threaded connection (NPT/BSPT/G), it allows tool-light installation without welding. Made of 304/316/316L stainless steel, it features high strength, corrosion resistance and long service life, widely used in petrochemical, HVAC, industrial, food and pharmaceutical systems.
Core Features
● High pressure rated: 1000 WOG (6.9 MPa), stable for high-pressure service.
● Multi-port control: T/L type balls for mixing, diverting, switching.
● Easy installation: standard NPT/BSPT/G threads, no welding.
● Premium material: forged stainless steel, corrosion-resistant.
● Reliable sealing: ANSI Class VI zero leakage.
● Flexible operation: manual / electric / pneumatic, ISO 5211 mounted.
● Wide temperature range: -20°C ~ 260°C.
Core Points for Installation & Maintenance
Installation Points
1.Confirm ball type (T/L), size, pressure, thread and material.
2.Clean threads and valve cavity before installation.
3.Use PTFE tape or thread sealant; tighten properly.
4.Reserve enough operation space for handle.
5.Perform pressure test per 1000 WOG standard before use.
Maintenance Points
1.Regular inspection for leakage, corrosion and operation.
2.Clean and anti-corrosive protection for exterior parts.
3.Replace seats and seals if leakage occurs.
4.For electric/pneumatic actuators: check motor, air supply and limit switches.
5.Do not repair under pressure.
Typical Application Scenarios
● Petrochemical: medium mixing, diverting, switching.
● Industrial Manufacturing: hydraulic system, cooling circuit.
● Municipal HVAC: water mixing and distribution.
● Food & Pharmaceutical: sanitary fluid control (316L).
● Gas & Energy: natural gas / LPG line switching.
