Overview
Industrial-grade cast iron horizontal check valve engineered for medium-pressure steam and water applications up to 220°C. Constructed with an IBR 86 to 93 Gr.A cast iron body in a straight pattern, featuring a bolted cover for internal access. Internal dynamic sealing is achieved through a renewable seat and disc utilizing AISI-410 stainless steel trim. Designed in compliance with BS:5153 standards, this unit supports a PN 16 pressure rating and connects via DIN 2533 RF flanged ends. Supplied, sized and serviced for steam and water pipelines across Nepal.
Features & Benefits
- Compliance with BS:5153 and explicit IBR certification ensures the valve's material traceability and hydrostatic integrity for steam generation and boiler feedwater pipelines.
- Renewable AISI-410 stainless steel seat and disc elements isolate high-wear components from the main body, significantly dropping total lifecycle cost by permitting in-line repair instead of full unit replacement.
- Bolted cover architecture grants maintenance crews direct overhead access to internals, expediting debris clearance or trim inspection without breaking flange joints.
- The straight-pattern cast iron (IBR Gr.A) body is optimized for horizontal pipeline installations, minimizing flow turbulence and resulting pressure drop across the valve.
- DIN 2533 RF standard flanges (PN 16) guarantee standardized structural mating dimensions, mitigating flange face distortion under thermal gradients typical in 220°C steam service.
