Offering comprehensive valve overhaul, machining, pressure validation, and smart instrument calibration services.
We specialize in rebuilding complex control, pressure relief, and industrial piping valves. Below is an overview of the core services we provide.
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.
We perform hydrostatic shell and seat leak testing according to API 598, ISO 5208, and ANSI standards. Every valve leaves with a stamped chart and certification report.
Calibration of safety pop valves, pilot systems, gas regulators, and pressure gauges using master calibration devices traceable to national standards.
