Brass Solenoid Valves Supplier in Pakistan

Solenoid valves give fast, automatic on/off control of flow using an electric coil that opens or closes the valve the instant it is energised. Fitted throughout industrial automation, water systems, air lines and machinery, they replace manual operation and let equipment be controlled remotely or by a timer or controller. A. Karimjee & Sons supplies brass solenoid valves from ½″ to 2″ in normally-closed and normally-open configurations, with 24V, 110V and 220V coils, for water, air and light-oil service.

Types We Supply & How to Choose

Solenoid Valve Types

Selection guide

Normally Closed (NC): Shut when de-energised and opens when the coil is powered — the standard choice for on/off lines that should fail closed on power loss.
Normally Open (NO): Open when de-energised and closes when powered — used where flow must continue if power is lost.
Direct-Acting: Opens against zero line pressure; suited to smaller orifices and low-flow lines.
Pilot-Operated (Diaphragm): Uses line pressure to shift a diaphragm for larger sizes and higher flow; needs a minimum pressure differential to operate.

Frequently Asked Questions

What is the difference between NC and NO solenoid valves?

A normally-closed (NC) valve is shut when there is no power and opens when energised; a normally-open (NO) valve is open with no power and closes when energised. NC is the common default, while NO suits lines that must keep flowing if power is lost.

What media can a brass solenoid valve handle?

Brass solenoid valves are suited to water, air and light oil. For aggressive, corrosive or sanitary media, a stainless steel or diaphragm valve is the better choice.

What is the difference between direct-acting and pilot-operated solenoid valves?

Direct-acting valves open regardless of line pressure and suit small sizes and low flow. Pilot-operated (diaphragm) valves use line pressure to operate, handling larger sizes and higher flow, but they need a minimum pressure differential to work.
