Flat gate valve without pilot hole

Product Overview

The Flat Plate Gate Valve without Pilot Orifice is a robust and reliable solution designed for high-pressure, high-temperature applications in oil and gas pipelines, water supply systems and industrial processes. Featuring a flat plate gate valve design with no pilot orifice to ensure minimum pressure drop, tight sealing and smooth operation, the valve is ideal for systems requiring full bore flow and zero leakage.

working condition

Oil and gas: pipeline isolation and wellhead control.

Water supply: mains isolation and flow control.

Industrial processes: high pressure fluid handling in chemical and petrochemical plants.

Power generation: isolation of steam and feedwater in power plants.

Main features

Flat Gate Valve Design
No pilot holes: ensures full bore flow with minimal pressure drop.
Tight seal: ANSI Class VI leakage rate for critical shutoff applications.
Smooth operation: flat gate valve design with low operating torque.

Valve Structure
Valve body materials: carbon steel (WCB), 316L stainless steel (CF8M), duplex stainless steel (UNS S32205).
Gate Material: 13% chrome stainless steel, Stellite alloy 6, or nickel-plated carbon steel.
Sealing: Graphite, PTFE or metal-to-metal (-40°C to 450°C).

Flow Rate Characteristics
Full bore design: zero flow restriction for maximum efficiency.
Flow coefficient (Cv): 500-5000 (DN50-DN600).
Pressure drop: Streamlined runners with minimal pressure drop.

Operating characteristics
Low-torque operation: opens and closes smoothly and with little effort.
Bidirectional sealing: Effective sealing in both flow directions.
Fire resistant design: API 607 certified for fire resistant applications.
