Direct Acting Pressure Reducing Valve Manufacturer & Supplier in India
Speciality Valve is a specialized Direct Acting Pressure Reducing Valve Manufacturer and Supplier in India, offering precision-engineered valves for steam, water, air, and process applications. Designed to international standards, our valves are compact, durable, and widely exported to the USA, Europe, GCC, and Africa.
Function & Working
Direct acting pressure reducing valves use a spring-loaded diaphragm or piston mechanism to regulate outlet pressure. As upstream pressure varies, the valve automatically adjusts to maintain a steady downstream output. With no pilot system required, these valves are simple, fast-acting, and ideal for installations where compact design and low maintenance are critical.
Advantages of Direct Acting PRVs
Accurate pressure regulation with quick response
Lightweight, compact construction without pilot assembly
Reduced maintenance requirements and long service life
Suitable for steam, water, compressed air, and non-corrosive gases
Available in multiple sizes, materials, and pressure classes
