Premium Industrial Valve Catalog
We repair, test, calibrate, and supply high-quality industrial valves from our certified workshop.
A control valve is a power-operated device used to regulate the flow of fluids (like gas, oil, water, or steam) by varying the size of the flow passage. As the primary final control element in a loop, it directly dictates process quantities like pressure, temperature, and liquid level.
pressure relief valves are hydraulically operated, pilot-controlled, modulating valves designed to maintain constant upstream pressure within very close limits. They are primarily used in waterworks, industrial, and fire protection systems to prevent high-pressure surges and damage to pipelines
The VENN RP-6 "Benten" is a highly efficient, pilot-operated piston-type steam pressure reducing valve (PRV) engineered primarily for building equipment, industrial steam circuits, and large-flow production lines. It is widely recognized for its compact design, rapid response to pressure changes, and stable downstream control.
A steam PRV (Pressure Reducing Valve) is a self-operating valve that lowers high-pressure steam from boilers or distribution lines to a safe, usable, and consistent lower pressure for heating or industrial processes, without needing external power.
A ball valve is a shutoff valve that controls the flow of liquids or gases using a pivoting, hollowed-out spherical ball. Turning the valve handle a quarter-turn (90°) aligns the hole with the pipe to allow flow, or blocks it completely.
Metal-to-metal butterfly valves use solid metal discs and seats, rather than soft polymers, to control flow. This specialized design handles extreme temperatures (up to 600°C), high pressures, and abrasive or corrosive fluids, providing highly durable, bi-directional shut-off in demanding industrial environments.
A gate valve (also known as a sluice valve) is a linear motion valve that uses a vertical barrier or 'gate' to start or stop fluid flow. They are designed to be fully open or fully closed, ensuring an unrestricted, straight-through pathway with minimal pressure drop.
A globe valve is a linear-motion valve primarily designed to stop, start, and regulate (throttle) fluid flow. It gets its name from its traditionally spherical, globe-shaped body, which features an internal baffle that separates the inlet and outlet.
A Pressure Vacuum Relief Valve (PVRV), or breather valve, is a crucial safety device used on storage tanks and vessels. It automatically opens to relieve excess internal pressure or vacuum caused by temperature changes, pumping, or filling/emptying, protecting the tank from structural damage while minimizing vapor emissions.
A steam DRV (Pressure Reducing Valve) is a self-operating valve used to automatically lower high-pressure steam from a main distribution line to a safe, usable lower pressure for heating or equipment. It balances internal spring tension against downstream steam pressure to maintain a steady, continuous flow rate.
A safety valve is a fail-safe device designed to automatically release excess pressure or temperature from a system (such as a boiler, pressure cooker, or industrial pipeline) when safe limits are exceeded. It prevents catastrophic equipment failures, explosions, and injuries.
