JBV-100 Ball Valve for Pressure Pipe
Ball valves are designed to give higher strength and integrity by using the same dynamic multi-ring gland system as in the needle valve, which when combined with the anti-blowout back seating stem, guarantees resistance to all operating processes and pressures.

JCV-100 High Pressure/Temperature Check Valve
Every check valve is factory tested for crack and reseal performance with a liquid leak detector. Every check valve is cycled six times prior to testing. Every valve is tested to ensure it seals within 5 seconds at the appropriate reseal pressure.

JNV-100 Stainless Steel Male Needle Valve
Needle valves provide reliable flow control for a range of applications using a variety of stem designs, flow patterns, materials, and end connections in designs such as integral-bonnet and union-bonnet. Metering valves provide the ability to make fine adjustments to accurately control system flow in low- or high- pressure, and low-, medium-, or high- flow applications.

JBBV-103 Block and Bleed Monoflange Valve
The Block and Bleed Monoflange represents a true technical and economical innovation. Differently from the old system composed by big size block valves, safety and on-off valves, draining and sampling, these monoflanges allow to reduce costs and spaces. The monoflanges can be realized in traditional AISI 316 L as standard or exotic materials when required. They have compact dimensions with consequent reduction of assembling costs.

JELOK 2-Way Valve Manifolds for Pressure Gauge Transmitter
JELOK 2-valve manifolds are designed for static pressure and liquid level applications.Its function is to connect pressure gauge with the pressure point. It is generally used in field control instruments to provide multi-channel for instruments, reduce installation work and improve system reliability.
-
JELOK 3-Way Valve Manifolds for Pressure Transmitterr
JELOK 3-valve manifolds are designed for differential pressure applications. 3-valve manifolds are composed of three interrelated three valves. According to the function of each valve in the system, it can be divided into: high pressure valve on the left, low pressure valve on the right, and balance valve in the middle.
-
JELOK 5-Way Valve Manifolds for Pressure Transmitterr
When working, close the two groups of checking valves and balance valves. If inspection is needed, just cut off the high pressure and low-pressure valves, open the balance valve and two check valves, and then close the balance valve to calibrate and balance the transmitter.

Air Header Distribution Manifolds
JELOK Series air header distribution manifolds are designed to distribute air from the compressor to the actuators on pneumatic instruments, such as steam flow meters, pressure controllers and valve positioners. These manifolds are widely used in industrial chemical processing, plastic processing and energy industries and are approved for low-pressure applications up to 1000 psi (threaded end connections).
