Founded in 1993, Era CO.,LTD has started its operation as a small production unit of plastic irrigation fittings in 90's in Taizhou, China. With relentless focus on Research &Development, skilled and experienced personnel coupled with continuous implementations in technology and infratructure.

ERA today has enlarged the scale of company who has a modern, vertically integrated production facilities covering a surface of over 2300 mu which including molding, plastic injection, metal stamping. electronic appliances and assembling lines with the production capacity of 1200,000 annual ouputs for filters, valves sprayers , drip irrigation pipes，mist sprayers as well as filtration systems，which making it one of the leading industries in the sector, providing high quality, cutting-edge water treatments and water filtration systems.

During the past few decades, we have grown up one of the top Irrigation System provider in China and have didicated ourselves to developing and manufacturing the qualified agricultural and commercial irrigation products.

Now, as a reliable manufacturer in this irrigation market, we supply worldwide with our brand name “ERA”. For customer satisfaction on service and product quality which we are providing, we have obtained certificate of ISO 9001 on quality assurance and qualified management system, as well as other safty certificates such as CE, GS, ROHS, REACH, UL and so on, our products have been designed, developed and manufactured in accordance with strict specifications. Until now, we have obtained more than 30 patents like industrial design, utility model, technology invention and so on.

We always abide by the value of"innovation & creation, customer orientation, dynamic & entusiasm, integrity and honesty". We apply the core competence"scientific and technological innovation"to make contribution to water conservation and industrial water recycling etc. We are devote to bring a better environment for the earth by our continuous efforts.

MANUAL PRESSURE REDUCING VALVE

ERA Pressure Reducing Valve is hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop.

FEATURE &ADVANTAGE

Line Pressure Driven，Hydraulically Controlled

Protects downstream systems

Opensfully upon line pressure drop

Engineered Plastic Valve with lndustrial Grade Design

Highly durable, chemical and cavitation resistant

No internal bolts and nuts

Simple In-Line lnspection and Service

High Flow"Y"Valve Body with” Look Through” Design

Ultra-high flow capacity, low pressure loss Unitized Flexible Supper Travel(FST)Diaphragm and Guided plug

Accurate and stable regulation with smooth closing

Requires low opening and actuation pressure

Prevents diaphragm erosion and distortion

TYPICAL APPLICATION

Pressure Reducing Stations; Systems Subject to Varying Supply Pressure.

HOW IT WORKS

Fully open position: When upstream pressure drops, the pilot blocks the supply pressure port and opens the drain port, venting the control chamber to the atmosphere. This fully opens the valve, minimizing head loss.

Modulating to close: The pilot switches upon pressurerise, blocking the drain port and opening the supply pressure port. This pressurizes the control chamber, forcing the valve to modulate closed.

Locked position: When sensed pressure is equal to setting, the pilot blocks both the drain and the supply pressure ports. This locks the pressure in the control chamber, freezing valve opening in its last position until conditions change.
