Batu Valve is one of the leading trunnion ball valve manufacturers in Turkey. All our trunnion ball valves have affordable price and low torque.
We produce trunnion ball valves up to 56" size and in the Class 150 - Class 2500 working pressure range. Connection ends can be flanged or butt welded. It can be produced from different materials according to the usage areas. Our trunnion ball valves are suitable for manual, gearbox, pneumatic actuator, hydraulic actuator and electric actuator use.

FIRE SAFE DESIGN WITH SECONDARY METAL SEAT
BatuValve ball valves have been subjected to fire tests in accordance with API 6Fa and ISO 10497 standards. Regardless of the soft seat material, they will likely be damaged when exposed to fire conditions. Batu offers a fire resistant design that can greatly prevent leaks from seals when valves are damaged by fire. The functions of the bearings before and after the fire test are as shown. If Teflon and O’ring materials are damaged, a metal-to-metal seal is formed between the secondary metal seat and the ball. The slot-to-body graphite seals, graphite body seals, and graphite gasket end caps are designed to withstand high temperature and will remain undamaged.
Burgman gaskets used in the stem, on the other hand, serve as a sealing function during fire, ensuring that the stem parts of our valves are fire resistant and complement the Fire Safe feature.

SINGLE PISTON EFFECT (SPE)
This is the standart seat type. When pressure is applied on both sides, SPE-SPE seats are pushed towards the ball with the effect of a piston, providing a tight closing and sealing. If the pressure in the stem cavity rises above the pressure on either side of the line while the valve is in the closed position, the seat on that side will be pushed back and the in-shell pressure will be released to the low pressure side of the line. Due to this feature, SPE type seats are also called “Self pressure relieving”, which releases high pressure by itself. Typical Fields of Application: Pipeline ball valves in fluid services where the pressure increase in the body cavity due to temperature changes is required.
DOUBLE PISTON EFFECT (DPE)
It is an optionally available seat type. DPE seats, whether the pressure comes from the valve body cavity or from the upper or lower side of the pipeline; In both cases, it is designed to be pushed towards the sphere by the piston effect. DPE seated valves do not automatically relieve pressure in the body cavity. For this reason, the use of a drain valve is recommended in fluid services. Typical application areas; where it is necessary to create an additional safety barrier between the upstream and downstream sides and where maintenance of the seats is not envisaged. It is also recommended for valves with welded body.
SINGLE PISTON - DOUBLE PISTON EFFECT (SPE-DPE)
On the upstream side of the line, the SPE seat provides self-pressure relief. On the downstream side, the DPE seat provides a double barrier in case the upstream seat is damaged. This configuration includes a preferred installation direction with the SPE seat facing up. With SPE-DPE configurations, the cavity pressure evacuation always takes place via the SPE seat side . Typical application areas: Riser valves, Pig launchers / receivers. The DPE seat provides double insulation to the Pig trap and also allows the body cavity to be automatically relieved if pressure builds up.
ANTI-BLOWOUT DESIGN
Our Ball valves are designed and manufactured in such a way that when the movement shaft holders and seals are removed, it will not be possible for the stem to go out of the valve due to the effect of pressure, as described by the standards. The stem is designed with a wide lower flange. In this way, the body cover part prevents the stem from dislodging and prevents a possible explosion. This feature allows the shaft seal to be replaced even when the valve is under pressure.
ANTI-STATIC DESIGN
Ball Valves used in flammable and combustible fluid circuits such as petrol, LPG, LNG must be protected against static electricity. The spring and ball used in the stem ensure that any static electricity that may occur is grounded to the pipeline. In this way, the electrostatic charge that may occur on the ball is prevented. BATU Ball Valves are designed and manufactured in accordance with these requirements.
DRAIN & VENT DESIGN
BatuValve ball valves are produced with drain and vent discharge outlets designed in accordance with the connection sizes described by the standards. When the valves are brought to the closed position, drain and vent outlets can be used to safely discharge the pressurized fluid or gas remaining in the body.
SEAT RING DESIGN
HIGH PRESSURE – LOW PRESSURE SEALING DESIGN
The sealing performance of the ball valves at higher pressures are more important than at low pressures. At high pressures, sealing is ensured by forming a good contact between the sealing ring and the ball surface with the effect of the fluid pressure applied from the back surface of the Sealing seat ring. When the pressure behind the ring reaches a low value, this contact force decreases. In this case, the spring force supporting the seat ring ensures enough force is applied so the contact between the sealing ring and the ball surface and the sealing function are maintained.
DESIGN
Batu Valve designs its products using sophisticated computer-aided design application software. It uses finite element analysis methods to analyze the structural integrity of its designs under real life application conditions. This allows product designs to be optimized and guarantees high strength. As every valve produced passes physical tests, it enables us to offer quality, faultless, leak free, competitive products to the customer and to create more customer satisfaction in general.
