Types of 2/2 Way Low Pressure Diaphragm Type Solenoid Valves
We manufacture normally-closed 2/2 way diaphragm solenoid valves in brass and stainless steel, in a range of port sizes suited to water distribution, irrigation and low-pressure gas systems.
Normally Closed (NC) Solenoid Valve
Remains closed in the de-energized state. Opens only when power is supplied to the coil. Ideal for systems where fluid flow must stop automatically during a power failure.
Normally Open (NO) Solenoid Valve
Stays open when not energized and closes when power is applied. Preferred in applications where continuous flow is the default operating condition.
Direct Acting Solenoid Valve
Operates without requiring any minimum inlet pressure. The solenoid coil directly lifts the diaphragm to open or close the valve — perfect for zero-pressure and very low-pressure applications.
Pilot Operated Solenoid Valve
Uses differential pressure within the system to assist valve operation. Suited for stable low-pressure systems with consistent inlet pressure.
Brass Body Solenoid Valve
Widely used for water, air, and light fluid applications. Offers good corrosion resistance and durability at competitive pricing.
Stainless Steel Solenoid Valve
Designed for aggressive media, chemical exposure, and hygienic process environments requiring high corrosion resistance.
How 2/2 Way Low Pressure Diaphragm Type Solenoid Valves Work
A 2/2 way solenoid valve has two ports — one inlet and one outlet — and two positions: open and closed. The “diaphragm type” refers to the flexible membrane inside the valve body that physically controls fluid flow.
When the solenoid coil is energized, it generates an electromagnetic field that pulls the plunger upward, lifting the diaphragm off its seat and allowing fluid to pass through. The moment power is cut, a return spring pushes the plunger back down, pressing the diaphragm against the seat and stopping flow instantly.
What sets low pressure diaphragm type solenoid valves apart is their ability to open and close at zero or near-zero inlet pressure without relying on system pressure to assist actuation, making them far more versatile for gravity-fed systems, RO plants, and low-head water distribution networks. As a dedicated manufacturer in Mumbai, Concorde Valves engineers each unit for fast response, leak-proof sealing, and extended coil life across continuous-duty applications.
Applications
These valves are used in water distribution networks, irrigation systems, low-pressure gas lines and automation systems where standard solenoid valves would fail to open reliably due to insufficient differential pressure.

Frequently Asked Questions
Answers to common questions about 2/2 way low pressure diaphragm solenoid valve, materials, sizing and selection.
A 2/2 way low pressure solenoid valve is a two-port, two-position valve that uses electromagnetic actuation to open or close fluid flow at low or zero inlet pressure. It operates via a flexible diaphragm that lifts or seats against the valve orifice based on coil energization.
These valves are commonly used in water treatment plants, RO systems, chemical dosing lines, HVAC systems, pharmaceutical processing, food & beverage plants, and irrigation automation — anywhere precise on/off control is needed at low or zero pressure.
Yes. Our direct-acting 2/2 way solenoid valves are specifically designed for zero differential pressure operation. Unlike pilot-operated valves, they do not require minimum inlet pressure to actuate — making them suitable for gravity-fed or low-head systems.
Yes. Concorde Valves offers customization in port sizes (1/4" to 2"), body materials (brass, SS, plastic), seal compounds (NBR, EPDM, Viton, PTFE), voltage ratings, and coil enclosure types including weatherproof and flameproof options.
We offer NBR (nitrile) for water and air, EPDM for hot water and steam, Viton for fuels and chemicals, and PTFE for aggressive chemical media and hygienic applications.
Our solenoid valve coils are available in 12V DC, 24V DC, 24V AC, 110V AC, and 230V AC — suitable for both PLC-controlled automation panels and direct mains connections.
With correct selection of seal material and operating conditions, our low pressure diaphragm solenoid valves are rated for millions of switching cycles. Periodic coil and diaphragm inspection ensures long service life with minimal downtime.
Yes. We supply across all major cities and industrial zones including Mumbai, Pune, Gujarat, Chennai, Hyderabad, Delhi, Bengaluru, and Kolkata — with pan-India logistics support.
It means the valve is engineered to open and close reliably even when there is little or no pressure differential across the valve, unlike standard pilot-operated solenoid valves that need a minimum differential pressure to function.
They are commonly used in water distribution, irrigation and low-pressure gas systems where pressure conditions vary or drop close to zero.
Concorde Valves manufactures 2/2 way low pressure diaphragm solenoid valves in brass and stainless steel bodies.
