Pilot Operated Diaphragm Type Pressure Reducing Valve for Steam

Overview

This pilot‑operated diaphragm steam pressure reducing valve features similar internal structure and working principle to Yoshitake GP‑2000. It comes with identical face‑to‑face installation dimensions, enabling direct drop‑in replacement without modifying existing pipeline layout. It effectively cuts renovation costs and on‑site construction workload for equipment upgrade and spare‑part retrofitting projects.

Designed to handle small‑to‑large flow‑rate steam conditions, this pilot‑operated pressure reducing valve is widely applied in building utility systems, HVAC air‑conditioning installations and diverse factory process systems. It delivers steady pressure regulation performance under variable steam flow working conditions.

Features

1. Large‑size diaphragm combined with external pressure‑sensing structure achieves highly stable downstream pressure control.
2. Maximum pressure‑reducing ratio up to 20:1, accomplishing pressure reduction in a single‑stage process, which saves the cost of two‑stage pressure‑reducing configuration.
3. High Cv value greatly improves flow capacity and regulating performance. Users can select valve body one or two nominal sizes smaller than conventional valves to meet working requirements, saving project investment.
4. Spherical sealing structure provides superior tight‑shut‑off performance and remarkably reduces internal leakage, conforming to ANSI Class IV leakage standard.
5. Key moving components are manufactured from stainless steel for enhanced corrosion resistance and service life. The adaptor‑type design allows convenient on‑site installation, disassembly and maintenance for both main valve and pilot valve.
6. Drop‑in replacement compatible with Yoshitake GP‑2000; same face‑to‑face installation length, no pipe cutting or rework required.

Applications

‑ Building utility & central heating systems
‑ HVAC and air‑conditioning steam supply systems
‑ General industrial factory steam process pipelines
‑ Commercial facility steam distribution projects
‑ Retrofit & spare‑part replacement for original Yoshitake GP‑2000 installations
