SS304 Duplex Basket Strainer

Quantity: 6 units Size: 2″, 2 1/2″, 5″, 6″, 8″ Vent: NPT Plug Drain: NPT Plug Class: 150 Connection: ANSI 150# Duplex strainer or twin basket strainer is a type of filter built into a fuel, oil or water piping system and it is used to remove large particles of dirt and debris.

3-Way Ball Valves

They can be used as diverter valves, where flow a single inlet is diverted to either of the two other ports as the outlet.

Interflow Butterfly Valve

Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow.

3-Way Actuator Valve

A 3-way control valve shuts off water flow in one pipe while opening water flow in another pipe. The actuator is connected to the exhaust passage, therefore spring force or gravity must return the rod to its original position.

64″ High Performance Double Offset Butterfly Valve with Electric Actuator

Valve installation for vacuum system.

Jacketing Ball Valve

The body is modified by adding oversize flanges to help the high temperature steam or oil flow over the valve ball & body parts to keep the media liquid.

Pneumatic Delval Butterfly Valve Series 44 WCB

All valves can be direct mounted with pneumatic actuators or electric actuators and accessories for complete automation options such as fail open/close and positioner controlled.

Expansion Of Oil Refinery Plant (ISBL)

Project is for expansion of oil refinery plant (ISBL) which involves process lines such as air, steam, water and oil. Sizes : Ball Valves (DN15 ~ DN200), Bellow Sealed Globe Valves (DN15 ~ Dn200), Gate Valves (DN15 ~ DN100). Pressure : Ball Valves (PN16), Bellow Sealed Globe Valves (PN40), Gate Valves Forged SS & WCB (150) / Forged Steel (800)

Knife Gate Valves

Designed mainly for on-off and isolation services in systems with high content of suspended solids. Especially beneficial for handling slurry, viscous, corrosive and abrasive media.

Physical Checking And Testing Of Valve Due To Flood Waters

For solenoid valve, disassembly and insertion of air to see if there are presence of water. Also to, test coil using voltmeter for current. For limit switch, disassembly to check for presence of water. For actuator, insert air to check stroke cycle.

Pneumatic Actuator Meca-Inox Ball Valve

For refinery plant and fractional plant. Refinery: 793pcs manual valve, 180pcs actuator valve. Fractional: 390pcs manual valve, 23pcs actuator valve.

Supplying Valves For Turbine

How to install? Here’s a short video on how we add on matching flange and also bolt & nuts.

Pneumatic DelVal High Performance B’fly Vlv Series 44 SS316

Valves mounted with manual overrides, Intermeq Electro Pneumatic Positioner. A butterfly valve regulates flow by starting, slowing, or stopping media. The disk opens and closes with a low-torque rotation of 90 degrees and works for any compatible application.

Doctrine Engineering (M) Sdn. Bhd. – Jacketing Ball Valve With Extended Handle

The Jackets assure consistent valve Heating or Cooling of the process media to prevent crystallization or seizing of flow media. The Jacketed Ball Valve (Heating Jacket Ball Valve) with very well design to help the high temperature steam or oil flow over the valve ball & body parts to keep the media liquid.

DelVal Series 44

Suitable for high vacuum applications like niagara filter dosing and ice condensing systems. Sizes varies up to DN1600 (64″).
